Only a bit biased (7)
I believe the answer is:
partial
'biased' is the definition.
(similar in meaning)
'only a bit' is the wordplay.
I cannot quite 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.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for partial that I've seen before include "Not complete or whole" , "Fragmentary" , "Not complete or total, maybe an eclipse" , "Biased or unfair" , "Showing favouritism" .)
