portion

POR-shun /ˈpɔːr.ʃən/

nounverbA2IELTSTOEFL

neutral

A part or share of a whole, specifically the amount of food allocated or chosen for one person at a single meal.

A portion is subjective and chosen by the diner, unlike a standardized 'serving size' defined by regulatory nutrition guidelines.

The story behind the word. Traced back to Latin 'portio' (meaning 'share, portion' or 'relation to a whole'), linked to the Latin verb 'partire' (to divide). It passed through Old French 'porcion' into Middle English, keeping its core focus on dividing a shared whole into individual allotments.
