Intend to reciprocate a bit of amiability (3)

I believe the answer is:
aim
'intend' is the definition.
(aiming is a kind of intending)
'reciprocate a bit of amiability' is the wordplay.
I cannot really understand how this works, but
'a' is found in the answer.
'bit' could be 'i' (resembles 1, a binary digit or bit) and 'i' is present in the answer.
A single letter 'm' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for aim that I've seen before include "Set sights on, say target" , "Point (a camera)" , "Aspire" , "Purpose, intention" , "Ambition or goal" .)
