Be inclined to need some sort of prop (4)
I believe the answer is:
lean
'prop' is the definition.
(I've seen this before)
'be inclined to need some sort of' is the wordplay.
'be inclined to' becomes 'lea' (I am not sure about this - if you are sure you should believe this answer much more).
'need' says to put letters next to each other.
'some' indicates the central letters.
'sort of' becomes 'kinda' (informal way of saying 'kind of').
The middle letter of 'kinda' is 'n'.
'lea'+'n'='LEAN'
Can you help me to learn more?
(Other definitions for lean that I've seen before include "Be inclined - not fat" , "bank" , "What Jack Sprat's wife couldn't eat" , "Unprofitable" , "Sir David - - (film director)" .)
