Sign of love to the French? (3)
I believe the answer is:
leo
'sign' is the definition.
(star sign)
'love to the french?' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'to' says to put letters next to each other (I've seen this in other clues).
'the french?' becomes 'le' ('the' in French).
'o' put after 'le' is 'LEO'.
'of' is the link.
(Other definitions for leo that I've seen before include "Man" , "Pope" , "Cancer, ___, Virgo" , "born in July or August" , "Lion constellation" .)
