One needing help in looking for EU complex? Definitely (4-4)
I believe the answer is:
four-eyes
'one needing help in looking' is the definition.
(four eyes means someone who needs glasses)
'for eu complex? definitely' is the wordplay.
'complex?' is an anagram indicator (I've seen 'complex' mean this).
'definitely' becomes 'yes' ('definitely' can be used to say 'yes').
'for'+'eu'='foreu'
'foreu' anagrammed gives 'foure'.
'foure'+'yes'='FOUR-EYES'
(Other definitions for four-eyes that I've seen before include "Rude term for a specs wearer" , "Derogatory word for one wearing spectacles" .)
