Moon’s changing? Granted - feeling sleepy? (9)
I believe the answer is:
somnolent
'sleepy?' is the definition.
(I've seen this in another clue)
'moon's changing? granted' is the wordplay.
'changing?' indicates an anagram.
'granted' becomes 'lent' (grant can mean to give or lend).
'moons' is an anagram of 'somno'.
'somno'+'lent'='SOMNOLENT'
'feeling' acts as a link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for somnolent that I've seen before include "drifting off" , "falling asleep" , "Lent moons (anag.)" , "Sleepy, drowsy" , "Comatose" .)
