The month for hawthorn (3)
I believe the answer is:
may
I believe this clue is a double definition.
'the month' is the first definition.
(May is an example)
'for hawthorn' is the second definition.
(may is a kind of hawthorn)
(Other definitions for may that I've seen before include "Could" , "'5 _____' (popular piece of music by Bach)" , "Time" , "Hawthorm blossom" , "Might" .)
