I believe the answer is:
lean
'ryan's daughter director' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lean that I've seen before include "Insufficient - incline" , "Incline; (of person) thin" , "Unproductive" , "Of meat, with little or no fat" , "Slim; veer" .)
