Physically delicate (5)
I believe the answer is:
frail
'physically delicate' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for frail that I've seen before include "Struggling to get about" , "Delicate, fragile" , "hobbling around?" , "Physically feeble" , "Feeble - basket" .)
