The answer is LEFT, four letters. It is the everyday word for what is still there after the rest has gone, as in two slices left, and the Sun’s mini crossword gave Remaining that very answer in 2026. OTHER takes five squares and UNUSED six, while RESIDUAL and LEFTOVER both take eight.
The left that remains is not the left hand
LEFT in this clue is the past participle of leave, and leave has an older meaning than going away. Old English læfan meant to allow something to remain in the same condition, to let it stay, and behind it sits a Germanic root meaning remain, the one that also gave German bleiben. So what is left is, quite literally, what has been allowed to remain. The sense of departing came later, around 1200, out of the idea of leaving something behind.
The direction left is a different word altogether. It comes from Kentish and northern forms of an Old English word meaning weak or foolish, because the left is usually the weaker hand. The usual Old English word for left was winstre, literally friendlier, a euphemism for a side long thought unlucky. The two words simply ended up spelled alike, and a clue about direction, politics or a baseball field is not this one.

TOGO is two words
The fill most likely to stump you is TOGO, which turned up as the Remaining answer in a 2025 New York Times grid. It is not the West African country. Read it as TO GO, the way an announcer says two minutes to go or a runner counts laps to go, and it means exactly remaining. Crossword grids run multiword answers together without spaces, so an entry like this one reads as a single unfamiliar word until you split it.
The same principle explains ELSE and OVER on the list. What else is there asks what remains, and left over is where OVER comes from. When a four-letter answer for remaining will not resolve into LEFT, try splitting it or completing a phrase before hunting for another synonym. The plain answers have mainstream backing too: OTHER appeared in the LA Times, and UNUSED went into a Telegraph quick crossword.
Remaining, sorted from LEFT to LEFTOVER
Match the count, then the part of speech.
| Letters | Answer | How it means remaining |
|---|---|---|
| 4 | LEFT | The everyday default |
| 4 | TOGO | Two words, to go |
| 4 | OVER | As in left over |
| 4 | ELSE | As in what else |
| 5 | OTHER | The remaining people or things |
| 6 | UNUSED | Not yet touched or spent |
| 7 | STAYING | The verb form, remaining behind |
| 7 | REMNANT | A leftover piece |
| 7 | UNSPENT | Money or energy still available |
| 8 | RESIDUAL | What remains after a process |
| 8 | LEFTOVER | Food, or anything surplus |
At eight squares, RESIDUAL and LEFTOVER share only the E in the second position, so almost any crossing separates them.
Remnant is Old French for remaining
REMNANT is the most literal answer on the list. It is a contraction of the older remenant, from the Old French remanant, the present participle of remanoir, to remain. In other words, remnant is simply remaining in French, squeezed down by English speakers. Its specific sense of the end of a bolt of cloth, the part left after the last cutting, is recorded from the mid-1400s, and the word still names the unsold end of a roll of fabric.
LEFTOVER is younger than it looks. The adjective is recorded from 1890, and leftovers for the excess food after a meal from 1878. Old English had its own word for that, metelaf.
Residual picked up a paycheck sense
RESIDUAL began in mathematics in the 1550s for a quantity left after subtraction, then widened around 1600 to anything remaining or left over. In the plural it picked up a working sense. Residuals, the royalties paid when a recorded performance or broadcast is shown again, are attested by 1960. STAYING is the other long answer worth a note, because it treats remaining as a verb form, as in remaining at home, rather than as an adjective. If the clue could describe an action, try the verb reading.
Frequently asked questions
What is the four letter answer for remaining?
LEFT is the standard four-letter answer. TOGO, read as the two words to go, also fits and has appeared in the New York Times, and OVER and ELSE turn up in older grids. Check a crossing letter before choosing between them.
Why is TOGO an answer for remaining?
Crossword answers ignore spaces, so TOGO is the phrase to go, as in two laps to go or ten minutes to go. In that use it means still remaining, and it has nothing to do with the country of the same name in West Africa.
Is REST an answer for remaining?
Not usually. REST is a noun meaning the remainder, while remaining is an adjective or a verb form, so grids answer it with LEFT, OTHER, UNUSED or STAYING instead. REST is the fill to try when the clue is the noun remainder itself.
