Usage

Plural word for no The plural form of no can be either nos or noes. The plurals of several other singular words that end in -o are also formed this way, as in mango/mangos/mangoes and mosquito/mosquitos/mosquitoes. In some instances, particularly in advertising and other public communications, the plural form of no is written with an apostrophe, as in no's. This is not considered standard, but it may be easier to understand in some contexts, because nos. (with a period at the end) is also used as an abbreviation for numbers and because many people are unfamiliar with the plural form of no. The word no is only pluralized when it is used as a noun rather than in its more common use as an adverb. The word no as a noun means "an answer or vote of no" or "a person who votes in the negative," as in The noes outnumbered the yeses.

Etymology

Origin of no1

First recorded before 900; Middle English no, na, Old English nā, from n(e) “not” + ā ay 1

Origin of no2

First recorded in 1150–1200; Middle English; variant of none 1

Origin of 5

1870–75; < Japanese, earlier noũ < Middle Chinese, equivalent to Chinese néng ability

Explanation

No is the ultimate negative: it means "not any," or "not at all," and it's also used to express a generally negative response. If there's no milk for your cereal in the morning, there's not a drop left. A sign in a school hallway that says "No running" means that it's absolutely not allowed. And, the response, "No, thanks" when you offer your friend half of your liverwurst sandwich means that she is really not interested. You might vote no on a special ballot question about extending school to Saturdays or exclaim, "Oh no!" to express disappointment when your team loses a big game. No comes from the Old English negative, na.
