I rowed nervously for this strange guy (6)
I believe the answer is:
weirdo
'this strange guy' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'i rowed nervously' is the wordplay.
'nervously' indicates anagramming the letters.
'i'+'rowed'='irowed'
'irowed' anagrammed gives 'WEIRDO'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for weirdo that I've seen before include "An eccentric (sl.)" , "Way-out person" , "Eccentric type" , "Bizarre character" , "Crank - oddball" .)
