personable

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

'and of good appearance' is the definition.
I can't judge whether this defines the answer.

'an individual competent' is the wordplay.
'an individual' becomes 'person' ('person' can be a synonym of 'individual').
'competent' becomes 'able' (similar in meaning).
'person'+'able'='PERSONABLE'

Can you help me to learn more?

(Another definition for personable that I've seen is " Pleasant to be with".)

I've seen this clue in the Evening Standard.
