apish

I'm a little stuck... Click here to teach me more about this clue!

'like a primate' is the definition.
I can't judge whether this defines the answer.

'his pa maybe' is the wordplay.
'maybe' indicates anagramming the letters.
'his'+'pa'='hispa'
'hispa' anagrammed gives 'APISH'.

Can you help me to learn more?
