Left eggs boiled initially by the French - adorable! (7)
I believe the answer is:
lovable
'adorable' is the definition.
(similar in meaning)
'left eggs boiled initially by the french' is the wordplay.
'left' becomes 'l' (common abbreviation).
'eggs' becomes 'ova' (term for egg cells).
'boiled initially' becomes 'b' (I can't justify this - if you can you should believe this answer much more).
'by' is a charade indicator (letters next to each other).
'the french' becomes 'le' ('the' in French).
'l'+'ova'+'b'+'le'='LOVABLE'
Can you help me to learn more?
(Other definitions for lovable that I've seen before include "Easy to be fond of like 21 Down" , "Adorable" , "Delightful" , "Inspiring affection" , "Attracting affection" .)
