Time to enter gorge, say (5)
I believe the answer is:
state
'say' is the definition.
('state' can be a synonym of 'say')
'time to enter gorge' is the wordplay.
'time' becomes 't'.
'to enter' means one lot of letters goes inside another.
'gorge' becomes 'sate' (I've seen this before).
't' inserted into 'sate' is 'STATE'.
(Other definitions for state that I've seen before include "Condition - sovereign political power" , "eg Rhode Island" , "Say; nation" , "Say; country" , "Pomp; nation" .)
