Find application made by the French, at heart, kind of seedy? (5,4)
I believe the answer is:
apple core
'kind of seedy?' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'find application made by the french at heart' is the wordplay.
'find application' becomes 'app' (I am not sure about this - if you are sure you should believe this answer much more).
'made by' is a charade indicator (letters next to each other) (letters written or made by another set of letters).
'the french' becomes 'le' ('the' in French).
'at' says to put letters next to each other.
'heart' becomes 'core' (synonyms).
'app'+'le'+'core'='APPLE CORE'
Can you help me to learn more?
