Synonym discussion

Sense: noun/1

For noun/1, packet usually means a small paper or cardboard container holding small goods for sale, such as seeds or biscuits. Pack is a very close everyday word and is often the more usual choice for cigarettes, cards, or groups of items sold together. Package is broader and can refer to almost any wrapped or boxed thing, so it is less specific. Parcel is mainly for something wrapped for sending, which matches sense 3 better than sense 1. Sachet is narrower still: it usually means a tiny sealed packet with one-use powder or liquid inside, so it fits sense 2. Compare: Nina bought a packet of seeds. The driver left a parcel at the gate. The cafe gave us two sachets of sugar.

Etymology

FrenchEnglish

Packet came into English from French paquet, which meant a small pack or bundle. That French form is related to pack, with a small-size ending added. Over time, English kept the basic idea of something gathered together in a small bundle, and later extended it to papers, units of computer data, and informal money uses.
