Etymology

Origin of portion

First recorded in 1250–1300; Middle English porcion, from Old French, from Latin portiōn- (stem of portiō ) “share, part,” akin to pars part

Explanation

If a friend asks you to invest in her new start-up in exchange for a portion, or part, of the company’s profits, consider the agreement carefully. Remember, a portion of zero is still zero. Portion can also refer to the amount of food provided for each person at a meal. If you’re reviewing a restaurant, for example, you'll want to take note of the portion size. In addition, portion can be used as a verb meaning “divide and distribute something.” At birthday parties, we find it odd that the person celebrating her birthday is expected to perform the annoying task of portioning her own cake (perhaps it’s so she can claim the biggest portion).
