The French love this forename (3)

I believe the answer is:

leo

I'm a little stuck... Click here to teach me more about this clue!

'forename' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.

'the french love' is the wordplay.
'the french' becomes 'le' ('the' in French).
'love' becomes 'o' (love means zero in tennis).
'le'+'o'='LEO'

'this' is the link.

Can you help me to learn more?

(Other definitions for leo that I've seen before include "Horoscope sign" , "Lion sign of the Zodiac" , "born in July or August" , "Zodiacal lion" , "sign of summer" .)
