Слово не воробей: вылетит — не поймаешь
Slovo ne vorobey: vyletit — ne poymaesh’ Word not sparrow: flies out — you will not catch A word is not a sparrow: once it flies out, you will not catch it.
A sparrow that gets into a house can be dealt with. It hits the window twice, settles on the curtain rail, and somebody opens the casement or fetches a towel. It takes ten minutes and a certain amount of shouting, but the bird is small, tired, and in a room. Russian keeps this scene in mind for the express purpose of saying that a word is nothing like it.
What it means
It is tempting to carry the proverb off as “a word is a sparrow,” and that gets it backwards. The Russian opens with a denial: слово не воробей, a word is not a sparrow. Then a colon, and the reason: вылетит — не поймаешь, it flies out, you will not catch it. Both verbs are perfective and both point forward. The first is the word’s, the second is yours, and yours carries the не.
So the sparrow is not the image of the word. It is the measure the word fails. The quickest, commonest, most uncatchable thing in a Russian yard is brought in only to be called the easier case. Whatever you have done about sparrows will not help you here.
The second person matters too. Russian uses the you-form for general truths, the way English uses “one,” but the effect is less polite. The sentence is not about speakers in general. It is already about you, a moment after you have said it.
Where it comes from
Vladimir Dal’ printed the proverb in 1862 in Poslovitsy russkogo naroda, in the section he titled «Язык — речь», tongue and speech. A 1989 Moscow edition of the collection also carries a slightly longer form, вылетит, так не поймаешь. How long it had been said before Dal’ wrote it down I have not been able to establish, and I would rather leave that open than guess at a century.
What Dal’s page does show is that the sparrow had competition. The same section holds a row of sayings making the identical point with other equipment. Коня на вожжах удержишь, а слова с языка не воротишь: a horse you can hold on the reins, a word you cannot turn back from the tongue. Слово выпустишь, так и крюком не втащишь: let a word out and you will not drag it back with a hook. Выстрелив, пулю не схватишь, а слово, сказав, не поймаешь: having fired, you will not grab the bullet. There is one about spit. Directly after the sparrow comes the saddest of them: И дорого б дал за словечко, да не выкупишь, you would pay dearly for that little word, and you cannot buy it back.
Russian had a horse, a hook, a bullet and a ransom to choose from, and it kept the sparrow. That is the one any Russian speaker now knows. My guess, and it is only that, is that the others are too serious. A bullet makes the speaker a killer; a ransom makes the speaker a penitent. The sparrow makes the speaker faintly ridiculous, standing in a yard with empty hands, and that is how having said the wrong thing mostly feels.
The flying word itself is much older than Dal’. Horace, advising a young friend on how to live among the powerful, tells him to avoid the man who asks too many questions, because ears that gape do not keep what they are given, et semel emissum volat irrevocabile verbum: and a word once let out flies beyond recall. Nothing I have found connects the Latin line to the Russian yard, and I am not claiming descent. Horace’s word simply flies. It took the Russian to give it a species, and a small brown one at that.
How it gets used today
In 2001 the philologist I. Golub answered a reader’s letter in the language column of Nauka i zhizn’, the long-running popular science monthly. The column is about fixed expressions and how people mangle them, and it ends on the proverb used straight, as a warning to the reader: do not forget, a word is not a sparrow. Along the way Golub reports having heard someone say «Слово не воробей, не вырубишь топором»: a word is not a sparrow, you can’t hack it out with an axe. The axe has plainly wandered in from another saying. Golub’s verdict is that as a joke it is fine.
Two things can be taken from that. The proverb is well enough known that its first half alone summons the rest, which is what lets the wrong ending be funny. And it is spoken mostly after the fact, or just before, as a caution; the column itself is an instance. What a given family does with it at a given table I can only infer.
Cousins from other tongues
The claim is narrow: what is said is out of the speaker’s reach the moment it is said. Each of these makes it, and each stands somewhere else to watch.
Chinese ran the same chase with better equipment and lost it the same way. In the Analects, a minister named Ji Zicheng remarks that a gentleman needs substance and has no use for polish. Zigong, Confucius’s disciple, winces on his behalf: a pity you put it so, sir — 駟不及舌, sì bù jí shé, a team of four horses cannot overtake the tongue. The pursuer is a chariot, the fastest thing an aristocrat owned, and it is his rank that fails to help him. The modern saying built on it, 一言既出，驷马难追, yī yán jì chū, sì mǎ nán zhuī, has since changed sides. The CC-CEDICT dictionary now glosses it with a second sense: a promise must be kept. The horses that could not catch the word have become a guarantee that nobody will try. Russian has made no such use of its sparrow. Nobody swears by it.
The other Chinese idiom removes the chase altogether. 覆水难收, fù shuǐ nán shōu, spilled water is hard to gather, goes back to a line in the History of the Later Han about a decision of state. A sparrow that has flown is still a sparrow; it is on a neighbour’s roof, alive, and audible. That is exact about words, which go on being repeated by other people. Water tipped on the ground is not anywhere. The Chinese image is about the end of something, and this site’s essay on it follows it into the ending of a marriage. The Russian is about something that has only just started and is now out of your hands.
Persian looks where the Russian never does. زخم زبان از زخم شمشیر بدتر است, zakhm-e zabān az zakhm-e shamshīr badtar ast: the wound of the tongue is worse than the wound of the sword. The sparrow proverb has one person in it. There is the speaker, the bird, and an empty sky, and no mention of where the bird comes down. The Persian begins at that point, with a second person and a cut, and says that the cut is the kind that stays open. It is the same permanence, reported by the one who was hit.
Why it matters
Dal’ gave the speaker a horse to hold, a hook to throw, money to offer. The proverb that outlived all of those gives the speaker nothing, and does not even grant the dignity of a real pursuit. It only asks you to remember the bird in the room, the window, the towel, how long that took, and then to notice that this time there is no room.
