IPA: /ˈɡreɪvər/
KK: /ˈgreɪvər/
A person or tool that carves or engraves designs into a surface, often used in art or metalwork.
The artist used a graver to create intricate designs on the metal plate.
Graver → It is formed from "grave" (from Old French *grave*, meaning serious or weighty) and "-er" (meaning a person who). A graver is a person who engraves or carves designs, often in a serious or detailed manner.
Think of someone who is 'serious' ('grave') about their work of engraving, and the '-er' indicates that they are a person doing that work.
