Ladies' fingers all right with artist (4)
I believe the answer is:
okra
'ladies' fingers' is the definition.
(ladies' fingers is a name for the okra plant)
'all right with artist' is the wordplay.
'all right' becomes 'ok' (synonyms).
'with' says to put letters next to each other.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'ok'+'ra'='OKRA'
(Other definitions for okra that I've seen before include "Bhindi in Ind. cookery" , "Ladies' fingers with edible pods" , "Edible seed pods" , "Long green tropical vegetable" , "Bhindi or lady's finger" .)
