Hoskins must be hugged by model? Cool! (5)
I believe the answer is:
poise
'cool' is the definition.
(I know that cool can be written as poise)
'hoskins must be hugged by model?' is the wordplay.
'hoskins' becomes 'I' (where the crossword setter is 'Hoskins').
'must be hugged by' means one lot of letters goes inside another (inserted letters get hugged).
'model?' becomes 'pose' (model can mean to pose).
'i' inserted into 'pose' is 'POISE'.
(Other definitions for poise that I've seen before include "Elegance" , "Sang-froid" , "Balance; composure" , "Grace; equilibrium" , "Dignity and assurance of manner" .)
