Artisan good with young lady on phone (11)
I believe the answer is:
glassblower
'artisan' is the definition.
(I know that glassblower is a type of artisan)
'good with young lady on phone' is the wordplay.
'good' becomes 'g' (abbreviation).
'with' is a charade indicator (letters next to each other).
'young lady' becomes 'lass' (lass is a kind of young lady).
'on' says to put letters next to each other (in a down clue, letters appear on others).
'phone' becomes 'blower' (informal term for telephone).
'g'+'lass'+'blower'='GLASSBLOWER'
(Another definition for glassblower that I've seen is " skilled craftsperson".)
