Steered clear of a useless fellow (7)
I believe the answer is:
avoided
'steered clear of' is the definition.
(I've seen this before)
'a useless fellow' is the wordplay.
'useless' becomes 'void'.
'fellow' becomes 'ed' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'a'+'void'+'ed'='AVOIDED'
Can you help me to learn more?
(Other definitions for avoided that I've seen before include "Shunned" , "Missed" , "Stayed clear of" , "Steered clear of" , "Kept away from" .)
