IPA: /ˈkreɪtəˌlɛt/
KK: /ˈkreɪtərˌlɛt/
A small hole or depression in a surface, often formed by an impact or explosion.
The moon's surface is covered with many craterlets, each telling a story of past impacts.
Craterlet is formed from "crater" (from Latin *crater*, meaning a bowl or vessel) and the diminutive suffix "-let" (meaning small). The word "craterlet" refers to a small crater, often used in geological contexts to describe minor depressions or holes.
Think of a 'crater' as a bowl-shaped depression and the '-let' as indicating something small, so a craterlet is simply a small bowl-shaped depression.
