fill — noun

Word family

Synonym discussion

Sense: verb/1

'Fill' is the general word for putting as much as possible into a container or space until it is full: you fill a glass with water or a room with people. 'Pack' suggests filling tightly and neatly, often with care or organisation — for example, packing a suitcase or packing a box with dishes. 'Stuff' implies pushing material in forcefully or carelessly, without much order, such as stuffing a pillow with cotton or stuffing clothes into a drawer. 'Load' focuses on putting a large quantity into something designed to carry it, like loading a truck with furniture or loading a washing machine with laundry. A useful distinction: you fill a cup (any liquid, no force needed), you pack a bag (organised arrangement), you stuff a turkey (forcibly fill a cavity), and you load a van (putting heavy items into a vehicle).

Etymology

Proto-Indo-EuropeanProto-GermanicOld EnglishEnglish

The word 'fill' comes from Old English 'fyllan', meaning 'to make full, fill up'. This can be traced back to Proto-Germanic '*fulljan', which was formed from '*fullaz' (full). The ultimate root is the Proto-Indo-European '*pel-' meaning 'to fill'. The core idea of making something full has stayed remarkably consistent over more than a thousand years of English.
