Untrimmed → It is formed from "un-" (meaning not) and "trimmed" (from Old English "trimman", meaning to make neat or tidy). The word "untrimmed" means not made neat or tidy, indicating something that has not been cut or shaped.
Think of 'not' ('un-') making something 'neat' or 'tidy' ('trimmed') — that's why untrimmed means it hasn't been made neat.
