Synonym discussion

Sense: noun/1

All four words name a flexible container, but they differ in size, material, and what you put inside. 'Bag' is the everyday choice and the broadest term — paper, plastic, or cloth, holding anything from sweets to bricks. 'Sack' is bigger, rougher, and made of cloth or strong plastic; it suggests heavy goods like coal, potatoes, or post for delivery. 'Pouch' is small and often closes with a string, zip, or button; think of a tobacco pouch, a coin pouch, or the pouch on a kangaroo. 'Packet' is sealed and usually holds a single product portion — a packet of biscuits, a packet of seeds. So you carry shopping in a bag, dump rubbish in a sack, keep coins in a pouch, and open a packet of crisps.

Etymology

Old NorseMiddle EnglishEnglish

The English word entered the language around 1200 from Old Norse 'baggi', meaning a pack or bundle, brought to Britain by Scandinavian settlers. The word's roots are uncertain — possibly Celtic — but its core idea of a flexible holder has been steady for eight hundred years. Verb senses ('to put into a bag', then later 'to capture' as a hunter puts game into a game bag) developed from the noun in the late 1500s, with the modern slang sense of 'to claim quickly' growing out of that hunting use.
