foible

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

'minor flaw' is the definition.
'foible' can be an answer for 'flaw' (thesaurus). I am not sure about the 'minor' bit.

'lie about love an empty lie' is the wordplay.
'lie' becomes 'fib' (fibbing is a kind of liing).
'about' means one lot of letters goes inside another.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'an empty' says to hollow out the word (remove centre letters).
'lie' with its centre taken out is 'le'.
'fib' enclosing 'o' is 'foib'.
'foib'+'le'='FOIBLE'

'is a' acts as a link.
