Pluralhalves
Pluralhalves
- 1One of two equal or nearly equal parts of something; the number or quantity equal to one divided by two.
She poured the batter, keeping half for the next day.
The two halves of the walnut shell fit together perfectly.
UsageSay half the class or half of the class for a quantity. The plural is halves.
Note
The core noun. Old English healf could mean a side or a part as well as a half, and the word still divides loosely in everyday use. Precision is optional, and the smaller half of an apple is perfectly idiomatic. The plural is halves, and in the idiom you don't know the half of it the word names an unmeasured share of the truth.

Note
Sports reckon time in halves as well as space: an association football match runs two halves of 45 minutes each, with a halftime interval between them. Added time is played at the end of each half, while extra time or overtime comes after both. Keep it apart from each side's end of the field, which divides the ground rather than the clock.

UsageOften joined to its noun with a hyphen: a half-truth, a half-smile, though open spellings like half truth also appear.
Similarpartial, incomplete
Note
Here the word is loose rather than exact: a half truth is not fifty percent true, only incompletely so. It often joins its noun with a hyphen, as in Tennyson's half-consent of 1847, though half truth is also written open. The sense leans toward fault and imperfection, where the exact fifty-percent adjective is neutral.

So for Richard and Barbara, Jeff and Kari, the impossibly varied collection of steps and halves that is another legacy of my father.
2016, Robert M. Herzog, A World BetweenNote
A slang clipping that drops the noun from half brother or half sister and lets the adjective stand alone. It is most at home in the plural, beside its partner steps: Robert M. Herzog's A World Between (2016) speaks of "the impossibly varied collection of steps and halves."

- 9A road race covering half the distance of a marathon, about 13.1 miles.
He set a personal best in last weekend's half.
Hundreds of runners signed up for the spring half.
Note
A runner's clipping, at home in race talk. Someone runs a half or signs up for the spring half, and the setting of training and finishing times does the work that marathon would otherwise do. The distance, about 21.1 kilometers, is exactly half a marathon. Among sports words it should not be confused with a half of a match.

UsageMostly in fixed phrases that often exaggerate: half dead, half starved, half asleep.
Similaralmost, nearly, practically, virtually
Note
Close to complete rather than partial. When Christopher Marlowe writes in Tamburlaine the Great, "To be a King, is halfe to bee a God," the king falls just short of godhood, not halfway to it. Context separates this sense from the "partly" adverb: half asleep leans toward asleep, while half done leans toward unfinished.

He said he'd call back at half three.
UsageHalf nine is short for half past nine (9:30). Use the full phrase to avoid confusion.
Note
British and Irish clock talk: half nine is 9:30, with past simply dropped. Speakers in Australia and North America say half past nine in full. The clipped form can mislead listeners who know the rarer "half before" reading, in which half seven means 6:30.

Note
James Herriot's All Things Bright and Beautiful (1974) has a half of bitter, and Bill Appleton's Wide Boy (2006) has a half of lager. The word can sound modest on purpose. Just a half turns down a full pint, and a swift half promises a short stop.

An old ticket-window word, British and now dated. Fares were spoken as a count, so two and a half to Paddington asks for two adult tickets and one child's ticket, not two and a half fares of anything. Today's phrasing is child ticket, and the elliptical half belongs to an earlier era of travel.
