Little creature a humble rustic could have with peas (3)
I believe the answer is:
ant
'little creature' is the definition.
'a humble rustic could have with peas' is the wordplay.
I cannot quite understand how this works, but
'a' could be 'an' and 'an' is located in the answer.
A single letter 't' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ant that I've seen before include "Social worker" , "Small busy insect" , "Proverbially hard-working insect" , "Industrious insect" , "Hill-dweller" .)
