Liu Yong

羁旅travel and sojourn 愁思melancholy 名篇celebrated masterpiece

长安古道马迟迟。
高柳乱蝉栖。
夕阳岛外，秋风原上，目断四天垂。
归云一去无踪迹，何处是前期。
狎兴生疏，酒徒萧索，不似去年时。

On Chang'an's ancient road my horse goes slow.
Tall willows where a riot of cicadas perches.
Sunset beyond the isle, autumn wind across the plain—my straining gaze breaks where the four skies hang low.
The homing clouds, once gone, leave not a trace; where now are the meetings once promised?
Passion's zest worn thin, my drinking friends scattered and few—nothing now as it was last year.

Listen

Meaning

Written on the ancient road to Chang'an, this lyric of travel dwells on autumn dusk and the sense of loss between past and present. The upper stanza builds a desolate scene—slow horse, tall willows with jangling cicadas, sunset and autumn wind beneath a sky descending on every side; the lower stanza confesses that past joys and old companions, like vanished clouds, can never be recovered. The closing line, 'nothing now as it was last year', distills the poet's feeling of aging and of all things changed.

长安古道上马儿缓缓前行。高高的柳树上，杂乱鸣叫的秋蝉栖歇其上。夕阳在岛屿之外，秋风在原野之上，放眼望去，四天垂地，望不到尽头。归云一去再无踪迹，何处才是从前约定的前程。冶游的兴致已经生疏，酒友也零落萧索，一切都已不像去年的时候了。

Appreciation

This is one of the peaks of Liu Yong's travel lyrics, excelling in vast scenery that carries feeling and in the contrast of now and then. The upper stanza is pure scene: 'slow' sets a weary pace that mirrors the heart, 'riot' doubles the cicadas' noise and the mind's disorder, and the three-beat line 'Sunset beyond the isle, autumn wind across the plain—my straining gaze breaks where the four skies hang low' has long been famous for painting boundless dusk. The lower stanza is feeling held deep: the vanished clouds stand for past pleasures and absent friends, the question 'where now are the meetings once promised?' for a road without prospect, and the final three short phrases weigh now against then. Not one word says 'sorrow', yet sorrow floods the whole—Liu Yong's 'plain words, deep feeling' at its purest.

【白话串讲】柳永写少年游：“长安古道马迟迟。高柳乱蝉栖”。“夕阳岛外，秋风原上，目断四天垂”——“归云一去无踪迹，何处是前期”——“狎兴生疏，酒徒萧索，不似去年时”——他写失意。【意象与手法】此词为柳永羁旅行役词中的名篇，写长安古道上的秋日之思与今昔之感。上片纯写景：古道、迟马、高柳、乱蝉、夕阳、秋风，意象苍茫萧瑟，「迟迟」「乱」「目断」诸字，写尽行路之缓、心境之乱、望眼之断；「夕阳岛外，秋风原上，目断四天垂」三句，由近及远，勾勒出天地苍茫、四望无际的黄昏图景，是柳永写景的千古名句。下片抒情：以「归云」一去无踪迹，暗喻往事与故人渺不可寻；「何处是前期」一问，写尽前路茫茫的怅惘；末三句「狎兴生疏，酒徒萧索，不似去年时」，以今昔对照收束，点出年华老去、人事全非的苍凉。全词景中含情、情由景生，语言明白而意境苍茫，是柳永词「状难写之景如在目前」的典范。【情感与主旨】此词写柳永羁旅长安古道时的迟暮之感与身世之悲。他一生潦倒，屡试不第，长期浪迹江湖，以词为生；此词以「马迟迟」起笔，写尽行旅的迟缓与心境的倦怠，以「目断四天垂」写天地茫茫、归路无期，以「归云一去无踪迹」暗喻往昔的欢乐与故人已不可追，末以「不似去年时」点明今昔之变。词中不见一个「愁」字，而迟暮飘零、前路茫茫之悲弥漫全篇，正是柳永「以淡语写深情」的本色，也是其羁旅词中境界最苍茫、感慨最深沉的篇章之一。【名句点睛】「夕阳岛外，秋风原上，目断四天垂」为千古名句：以三个「二、三、五」字句的短长错落，勾勒出夕阳秋风、四天垂地的苍茫画境，写尽天涯倦客望断天涯的惆怅，是宋词中写黄昏羁旅之景最苍凉的笔墨。

Background

Liu Yong (c. 987–c. 1053), originally named Liu Bian and called Liu Qi from his seventh place in the family birth order, was the leading graceful (wanyue) lyricist of the Northern Song. He failed the examinations repeatedly in his youth and lived among songhouses and wine shops writing for singers—his lyrics were sung wherever there was a well with a bucket rope—and only late in life, after changing his name, passed the jinshi, ending as a minor official popularly called Liu Tuntian. Restless official travel filled his years, and this lyric was written on the ancient road at Chang'an (modern Xi'an), the former Han and Tang capital that, though no longer the seat of empire, remained a great northwestern town and a symbol of vanished glory. Facing sunset, autumn wind and withered cicadas along the ancient road, he naturally felt both a mourner's awe for history and grief for his own drifting. The tune name 'Song of Youth' carries its own irony: the youthful revels of 'passion's zest worn thin, drinking friends scattered' are now gone, and the lyric's sense of 'not as it was last year' is at once private aging and the miniature of a luck-whipped life—one of the deepest-felt pieces among his travel lyrics.

柳永（约九八七—约一零五三），字耆卿，原名三变，因排行第七又称柳七，北宋婉约词派的代表词人。他早年屡试不第，放荡不羁，流连于歌楼酒肆，为乐工歌妓填词，其词传唱极广，以至「凡有井水处，即能歌柳词」。晚年改名永，方中进士，官至屯田员外郎，世称柳屯田。柳永一生漂泊，长期羁旅行役于各地，此词即写其在长安（今陕西西安）古道上的秋日情怀。长安为汉唐故都，北宋时虽已失去都城地位，仍是西北重镇与文化象征；柳永行经长安古道，面对夕阳秋风、古道残蝉，自然生出对历史的凭吊与对自身飘零的感慨。词题「少年游」为词牌名，而「少年」二字亦暗含对青春往事的追怀——当年冶游狎妓、呼朋引伴的少年意气，如今已「狎兴生疏，酒徒萧索」，繁华如梦，往事如烟。此词当作于柳永中年以后、宦游羁旅途中，词中「不似去年时」的今昔之感，既是个人年华的流逝，也是其一生潦倒命运的缩影，是柳永羁旅词中感慨最为深沉的作品之一。

Art

The lyric's art lies in vast scene-painting, feeling revealed through scenery, and the contrast of now and then. The upper stanza unfolds layer by layer: 'On Chang'an's ancient road my horse goes slow' sets the slow pace of travel—slow horse, weary heart; 'Tall willows where a riot of cicadas perches' makes 'riot' write both the jangle of the cicadas and the turmoil of the mind, object and self fused; 'Sunset beyond the isle, autumn wind across the plain—my straining gaze breaks where the four skies hang low' moves from near to far and from low to high, and the single word 'breaks' carries the ache of eyes that search to the limit and find nothing. The lower stanza is subdued and deep: 'The homing clouds, once gone, leave not a trace' figures the past and old friends gone beyond recall; 'where now are the meetings once promised?' writes the double loss of road and promise; and 'Passion's zest worn thin, my drinking friends scattered and few—nothing now as it was last year' seals the change of all things by weighing present against past. Upper stanza scene, lower stanza feeling, each the outward face of the other; plain speech throughout, yet the mood is fathomless—the practice of Liu Yong's dictum of 'describing the scene hard to describe, conveying the feeling hard to convey'.

此词在艺术上以「写景苍茫、以景见情、今昔对照」见长，是柳永羁旅词的艺术高峰。上片写景，层层展开：起句「长安古道马迟迟」以「迟迟」二字写行旅之缓，马行迟缓，正是人心倦怠的写照；「高柳乱蝉栖」写秋蝉栖于高柳，「乱」字既写蝉声之杂乱，亦写心绪之烦乱，物我交融；「夕阳岛外，秋风原上，目断四天垂」三句，由近及远、由下而上，夕阳在西，秋风在原，放眼四望，天幕低垂，苍茫的黄昏图景中，一个「断」字写尽望眼欲穿而无所见的惆怅。下片抒情，含蓄深沉：「归云一去无踪迹」以归云喻往事故人，一去不返；「何处是前期」一问，写前路与旧约俱渺不可寻；「狎兴生疏，酒徒萧索，不似去年时」三句，以今昔对照收束，点出人事全非。全词上片写景、下片言情，景之苍茫与情之苍凉相表里，语言明白如话而意境深远，正合柳永「语浅情深」的词风，亦是其「状难状之景，达难达之情」词学主张的实践。

Allusions

The lyric almost never uses allusion on the surface, yet its images are steeped in the literary tradition. 'Chang'an's ancient road': the former capital was from old the emblem of splendor and fame, and of parting (the willow-breaking at Ba Bridge); Liu Yong passing along its ancient, desolate way implies mourning for history's rise and fall and measures himself by the place—yesterday's ground of youthful revels, today's road of aging travel. 'Tall willows and jangling cicadas': autumn cicadas in willows are stock imagery of autumn, as in Luo Binwang's Cicadas, Sung in Prison; 'riot' writes both the noise and the turmoil of heart, inheriting tradition with new intent. 'Sunset' and 'autumn wind': the two images that most readily summon the sense of twilight and autumn grief, from the 'chill days' of the Book of Songs to Cao Pi's 'cold blows the autumn wind's weather'; Liu fuses both into one vast dusk—the 'grieving autumn' tradition at its utmost in the lyric. 'Homing clouds': the Songs of Chu and Tao Yuanming's 'clouds without intent leave the peaks' make clouds figures of human meeting and parting; 'gone without a trace' makes the cloud a figure of friends and joys past recall. 'Drinking companions': from Li Yiji of the early Han, self-styled 'the toper of Gaoyang', hence boon companions of the bottle now scattered. The images carry tradition without being stuck in allusion—natural and whole, the 'unblocked' character of Liu Yong's lyric.

此词几乎不用典故字面，而于意象中暗含深厚的文学传统。其一，「长安古道」：长安为汉唐故都，自古是繁华与功名的象征，也是离别的意象（灞桥折柳）；柳永行经长安古道，古道荒凉，暗含对历史兴废的凭吊，亦以其地自况——昔日少年游冶之地，今成迟暮羁旅之途。其二，「高柳乱蝉」：秋蝉鸣柳是古诗写秋的常景，如骆宾王《在狱咏蝉》以蝉自况；「乱」字写蝉声之嘈杂，暗喻心绪之纷乱，承传统而自有新意。其三，「夕阳」「秋风」：二者皆是中国诗歌中最能引发迟暮与悲秋之感的意象，《诗经》「秋日凄凄」、曹丕《燕歌行》「秋风萧瑟天气凉」，皆以秋景写愁思；柳永「夕阳岛外，秋风原上」，融二象于苍茫一图，正是「悲秋」传统在词中的极致。其四，「归云」：《楚辞》有「云容容兮而在下」，古诗常以云之去留喻人生聚散，陶渊明「云无心以出岫」尤著；「归云一去无踪迹」，以云喻人，写故人往事的不可追寻。其五，「酒徒」：汉初郦食其自称「高阳酒徒」，后世以酒徒指嗜酒纵乐之人；「酒徒萧索」写当年共饮之友零落星散。全词以意象承传统而不滞典故，天然浑成，正是柳永词「不隔」的本色。

Commentary

This is a famous piece among Liu Yong's travel lyrics, and critics have always prized the vastness of its upper stanza's scenery and the depth of its feeling. The Qing judgment that Liu could 'describe the scene hard to describe and convey the feeling hard to convey' finds its footnote here: 'Sunset beyond the isle, autumn wind across the plain—my straining gaze breaks where the four skies hang low' sketches the boundless dusk in the sparsest strokes, its breadth and desolation rarely matched in Song travel lyrics and prized as a famous scenic line. Compared with Fan Zhongyan's 'azure skies, yellow leaves, autumn colors joining the waves', Fan's autumn is bright and open where Liu's is bleak and vast; compared with Wen Tingyun's 'cockcrow, thatched inn, moon; footprints, plank bridge, frost', Wen piles dense objects for the hardship of the road while Liu spreads sparse images for its sorrow—the one dense, the other open. The lyric's value lies in merging personal travel grief with the historic associations of Chang'an into a universal desolation before heaven and earth; and the last line, in utterly plain words, says all there is to say about how completely things have changed, leaving a long aftertaste—one of the highest-reached and deepest-felt pieces in Liu Yong's corpus.

此词是柳永羁旅词中的名篇，历代评家极赏其上片写景之苍茫与全词感慨之深沉。清人评柳词「状难状之景，达难达之情」，此词正是注脚：「夕阳岛外，秋风原上，目断四天垂」三句，以极简的笔墨勾勒出天地苍茫的黄昏画境，其境界之开阔苍凉，在宋词羁旅题材中罕有其匹，被推为写景名句。与范仲淹《苏幕遮》「碧云天，黄叶地，秋色连波」相比，范词写秋景明丽开阔，柳词写秋景苍茫萧瑟，同是宋词写秋名篇而气象各异。与温庭筠《商山早行》「鸡声茅店月，人迹板桥霜」相比，温诗以密集的物象写羁旅之苦，柳词则以疏朗的意象写羁旅之悲，一密一疏。此词的价值，在于以「长安古道」这一历史象征为背景，把个人羁旅之愁与历史兴废之感融为一体，写出了天涯倦客面对苍茫天地时的普遍惆怅；末句「不似去年时」更以极平淡之语道尽人事全非之慨，余味悠长，是柳永词中境界最高、感慨最深的篇章之一。

Prosody

Form Lyric song (ci) to the tune 'Shaonian You' (Song of Youth): double stanza, fifty characters; upper stanza five lines with three level rhymes, lower stanza five lines with two level rhymes词（《少年游》，双调五十字，上片五句三平韵，下片五句两平韵）

Rhyme Level-tone qimei rhyme group: chi, qi, chui, qi, shi, one rhyme throughout; the rhymes are low and lingering, matching the vast twilight mood押平声「齐微」韵：迟（chí）、栖（qī）、垂（chuí）、期（qī）、时（shí），一韵到底，韵脚低回悠长，声情与苍茫迟暮之境相称。

Tone pattern Upper stanza line lengths of five, five, three, three and five characters, pleasingly varied; lower stanza five, six, three, four and five. Dominated by short lines at a slow tempo like the horse's pace; the paired three-character phrases 'beyond the isle / across the plain' give a forceful check, and the five-character close stretches out the resonance上片句式「五、五、三、三、五」错落有致，下片「五、六、三、四、五」长短相间。全词以短句为主，节奏沉缓，如马行之迟迟；「夕阳岛外，秋风原上」两个三字句对举，顿挫有力，「目断四天垂」以五字收束，拖长余韵，声情与词境相合。

Reading note 'Shaonian You' is a double-stanza short lyric of fifty characters, upper stanza five lines with three level rhymes and lower stanza five lines with two, its line lengths pleasantly uneven—a tune well suited to the idle sorrow of travel. Liu Yong's chief craft here is writing slowness with sound and sorrow with rhyme: the two five-character openings ('On Chang'an's ancient road my horse goes slow', 'Tall willows where a riot of cicadas perches') set a slow tempo answering the horse's slow pace; the paired three-character phrases 'beyond the isle / across the plain' check the movement like two long gazes into the distance; and the five-character close stretches the resonance of far-gazing to the horizon. In the lower stanza the seven-character 'The homing clouds, once gone, leave not a trace' and the five-character question 'where now are the meetings once promised?'—one sigh, one question—let the sound rise and fall; the last three lines, of three, four and five characters lengthening by steps, deepen like successive sighs, closing on the long aftertone of 'year'. In rhyme, the feet chi, qi, chui, qi, shi, all of the level-tone qimei group, are low and lingering, in keeping with the vast twilight scene. Plain speech with exquisite prosody and well-varied line lengths, the lyric is a model of Liu's 'writing feeling through sound', showing his deep craft in the short form.《少年游》为双调小令，五十字，上片五句三平韵，下片五句两平韵，句式长短错落，是宋词中适宜写羁旅闲愁的词牌。柳永此词在声律上最见匠心者，在于以声写缓、以韵写愁：上片「长安古道马迟迟」「高柳乱蝉栖」两个五字句起，节奏沉缓，正合行旅之迟迟；「夕阳岛外，秋风原上」两个三字句对举，短促顿挫，如目光的两次远眺；「目断四天垂」以五字拖长，把远望的余韵拉向天地尽头。下片「归云一去无踪迹」七字、「何处是前期」五字，一问一叹，声情跌宕；末三句「狎兴生疏，酒徒萧索，不似去年时」，由三字、四字、五字渐次加长，如叹息之渐深，收束于「时」字的悠长余韵。用韵上，押平声齐微韵，韵脚「迟」「栖」「垂」「期」「时」皆低回悠长，与苍茫迟暮的词境相合。全词语言明白如话而声律精工，长短句错落有致，是柳永「以声写情」的典范，可见其于小令声律上的深厚功力。

Line by line

长安古道马迟迟。

On Chang'an's ancient road my horse goes slow.

长安古道上，马儿缓缓前行。

On the ancient Chang'an road, the horse goes slowly.

起句写行旅之景，是全词的基调所在。「长安」二字点明地点，汉唐故都的繁华往事暗藏其中；「古道」二字写道路之古旧，既实写眼前之路，亦暗喻历史的沧桑；「马迟迟」三字是全句之神，「迟迟」写马行迟缓，而马之迟缓正是人心倦怠、前路茫然的外化——不是马不愿走，而是人无意前行。此句以极简的笔墨，写出天涯倦客的疲惫与犹豫：行至长安古道，面对苍茫前程，脚步沉重，内心茫然。全词的苍凉基调、迟暮之感，皆由这五个字奠定；后文高柳乱蝉、夕阳秋风、目断四垂，都是这「迟迟」行旅中的所见所感，故起句虽只五字，实为全词立骨。柳永善以寻常语写深切情，「迟迟」二字以缓写倦，尤见功力。

The opening writes the traveling scene, the whole ci's tone base. The Chang'an two words naming the place, the Han-Tang old capital's splendor past secretly within; the ancient road two words writing the road's oldness, at once the present road's real writing, and the history's vicissitudes metaphor; the horse-goes-slowly three characters the whole line's spirit, the slowly writing the horse's slowness, and the horse's slowness precisely the heart's weariness and the road-ahead's blankness externalization — not the horse's unwillingness to go, but the man's no-will-to-advance. This line, in the extreme brief brush, writing the horizon-weary traveler's exhaustion and hesitation: arriving at the Chang'an ancient road, facing the vast future, the step heavy, the heart blank. The whole ci's bleak tone and the evening-feeling, all established by these five characters; the below's high-willow chaotic cicadas, the setting-sun autumn wind, and the gaze-failing-the-four-sides, all this slowly traveling's seen and felt, hence the opening though only five characters, in truth the whole ci's bone. Liu Yong's craft of writing deep feeling through the ordinary words, the slowly two words' slow-writes-weariness, the craft the more seen.

夕阳岛外，秋风原上，目断四天垂。

Sunset beyond the isle, autumn wind across the plain—my straining gaze breaks where the four skies hang low.

夕阳在岛屿之外，秋风在原野之上，放眼望去，四天垂地，望不到尽头。

The setting sun beyond the isles, the autumn wind over the plain; my gaze fails where the four skies droop to the earth.

这三句是全词写景的千古名句，勾勒出黄昏羁旅的苍茫画境。「夕阳岛外」写落日悬于岛屿之外，视线由近及远；「秋风原上」写秋风吹过原野，点出节候与空间；「目断四天垂」收束一笔：极目远望，四天垂地，天地相接，茫茫无际。「目断」二字是全句之眼，写望眼欲穿而无所见，既无归鸟，亦无归人，唯见天幕四垂，把羁旅者的孤寂与怅惘写到极致。三句的节奏为「二、三、五」，短长错落，如目光由点及面、由近及远地扫过天际，最终定格在天地苍茫处；「垂」字写天幕低垂，仿佛压在心头的愁绪。以景写情，不着一个「愁」字，而愁已弥漫天地，正是柳永「状难状之景，达难达之情」的典范。

These three lines are the ci's scenic through-the-ages famous line, sketching the dusk-traveler's vast picture realm. The setting sun beyond the isles writes the sinking sun's hanging beyond the isles, the sight from near to far; the autumn wind over the plain writes the autumn wind's sweeping the plain, naming the season and the space; my gaze fails where the four skies droop to the earth the gathering stroke: the extreme gazing, the four skies drooping to the earth, the heaven-and-earth meeting, the boundlessness. The gaze-fails two words the whole line's eye, writing the gazing-to-the-uttermost and yet the nothing-seen, neither the returning bird nor the returning person, only the sky's four drooping edges, writing the traveler's loneliness and wistfulness to the extreme. The three lines' rhythm the two-three-five, the short-long uneven, like the sight from point to face and from near to far sweeping the horizon, finally fixed at the heaven-and-earth vastness; the droop word writing the sky's low hanging, as if the grief pressing on the heart. Writing feeling through scene, not one grief word, and the grief already filling heaven and earth, precisely Liu Yong's shape-the-hard-to-shape-scene and express-the-hard-to-express-feeling model.

归云一去无踪迹，何处是前期。

The homing clouds, once gone, leave not a trace; where now are the meetings once promised?

归云一去再无踪迹，何处才是从前约定的前程。

The home-bound cloud gone and leaving no trace; where is the day we once promised?

这两句由上片的写景转入下片的抒情，是全词由景入情的枢纽。「归云一去无踪迹」以云喻人喻事：天上的云一去不返，如同往昔的欢乐、故人、青春，都已无迹可寻。「归云」二字兼有「归」与「去」的矛盾——云欲归而终去，正写尽人事的无奈；「无踪迹」三字更添一层决绝，连影子都寻不着。「何处是前期」一问承上：前期指从前约定的前程，亦指旧日的期望与归宿；云去无迹，前期亦渺不可寻，这一问写尽前路茫茫的怅惘与失落。两句以云起兴、以问作结，把个人的身世之感寄托于自然物象，含蓄而深沉。与上片「目断四天垂」相呼应：目断是望不见归途，何处是前期是问不到归期，景与情、问与望，浑然一体，是柳永羁旅词中情景交融的典范。

These two lines from the first stanza's scene turn to the second stanza's lyric, the ci's scene-to-feeling hinge. The home-bound cloud gone and leaving no trace figures the person and the affair through the cloud: the sky's cloud once gone and not returning, just like the past joy, old friends, and youth, all the trace's unfindable. The home-bound cloud two words at once the return and the going contradiction — the cloud's wishing-to-return and yet the final going, precisely exhausting the affairs' helplessness; the no-trace three characters one layer more of decisiveness, even the shadow's unfindable. Where is the day we once promised? the question inherits: the day we once promised meaning the past agreed future, and the old expectation and lodging; the cloud gone and the trace's absence, the promised day also the blurred unfindable, this question exhausting the road-ahead vastness's wistfulness and loss. Two lines, rising on cloud and closing on question, entrusting the personal fate feeling to the natural image, restrained and deep. Echoing the first stanza's gaze-fails-the-four-sides: the gaze-fails the no-seeing-the-return-road, where-is-the-promised-day the no-asking-the-return-date, scene and feeling, question and gaze, fused as one, Liu Yong's travel ci's scene-feeling fusion model.

Study

Word focus

迟迟 'Chichi' (slow, lingering) describes the horse's pace but really the rider's weary, hesitant heart—not that the horse will not go on, but that the man has no wish to press forward—writing the man through the animal in flat words with a deep aftertaste, the key that sets the lyric's whole desolate tone. 「长安古道马迟迟」之「迟迟」二字，是全词基调的奠定者，亦柳永以缓写倦的妙笔。「迟迟」本指缓慢、迟缓，此处写马行之缓，而妙在不止写马：马之所以迟迟，正因人心倦怠、前路茫然，无意催行。此二字以马写人、以物写心，把羁旅者的疲惫、犹豫、茫然全部凝于马行的缓步之中，含而不露，深而不晦。同时，「迟迟」与「长安古道」相配，古道之古与马行之缓互相映衬，历史的苍茫与行旅的迟滞交织，使起句便笼罩在一种沉重的氛围里。若换作「踟蹰」「徘徊」等字，则直露心境，失却以物写心的含蓄；唯「迟迟」二字，写的是马，见的是人，语极平淡而味极深长，是柳永「语浅情深」词风的典范，亦为全词苍凉基调立下基调。

目断 'Mu duan' (the gaze breaks) means to strain the eyes to the very limit of sight and find nothing: the gaze is exhausted and so, in effect, severed—vision's limit becoming despair of return—held in a single word, and with 'the four skies hang low' it shuts the traveler beneath a drooping canopy, the most incisive diction in the poem. 「目断四天垂」之「目断」二字，是全词写景之眼，写尽望眼欲穿的惆怅。「目断」即望断、极目远望而望不到头，着一「断」字，把目光的穷尽与心绪的断绝融为一体：不是望不见，而是望到尽头仍无所见，目光断了，心也断了。此二字之妙，在于以「断」写「望」的极致——望到极点，唯见四天垂地，天地之间空无一物，唯余孤身旅人；「断」字既写视觉的穷尽，亦写归望的绝望，与「四天垂」相配，天幕低垂如罩，把旅人困于其中。若换作「目尽」「远望」等字，则只写动作，不见情绪；唯「目断」二字以断写望，望中有愁、断中有悲，把羁旅者面对苍茫天地的孤寂与无望写得力透纸背，是柳永炼字「以一字传神」的典范，亦是宋词中写羁旅愁思最精警的用字之一。
