Define (verb); e.g. Could you please define that for me? Give me a definition.
Definite (adjective); e.g., They gave us a definite answer. They said, "No".
Specific (adjective); e.g., You should ask a specific question.
specify (verb); e.g., Specify (i.e, clearly state) the books you took your information from.

Grammar correction:
Would you explain it to me? Thanks.

Hope that helps.
