Fine just to describe daughter with affection (6)

I believe the answer is:

fondly

'with affection' is the definition.
(I've seen this in another clue)

'fine just to describe daughter' is the wordplay.
'fine' becomes 'f' (abbreviation in pencil classifications).
'just' becomes 'only' (synonyms).
'to describe' means one lot of letters goes inside another.
'daughter' becomes 'd' (genealogical abbreviation).
'only' enclosing 'd' is 'ondly'.
'f'+'ondly'='FONDLY'

I've seen this clue in The Telegraph.
