Article on love for the little man (4)
I believe the answer is:
theo
'little man' is the definition.
'theo' can be an answer for 'man' (I've seen this before). I am unsure of the 'little' bit.
'article on love' is the wordplay.
'article' becomes 'the' (the definite article).
'on' is a charade indicator (letters next to each other) (in a down clue, letters appear on others).
'love' becomes 'o' (love means zero in tennis).
'the'+'o'='THEO'
'for the' is the link.
Can you help me to learn more?
(Other definitions for theo that I've seen before include "boy?" , "Man" , "Fellow" , "Kojak" .)
