A person whose job is to make, sell, or fix hats.
The hatter created a beautiful custom hat for the wedding.
Hatter → The word 'hatter' comes from the Old English 'hættere', which is derived from 'hæt' (meaning hat) and the agent suffix '-er' (meaning a person who). A hatter is therefore a person who makes or sells hats.
Think of someone who makes or sells 'hats' ('hæt') — the '-er' just means a person. This helps you remember that a hatter is someone who works with hats.
