Scholar in fresh air catching bees (5)
I believe the answer is:
rabbi
'scholar' is the definition.
(I've seen this before)
'fresh air catching bees' is the wordplay.
'fresh' indicates anagramming the letters.
'catching' means one lot of letters goes inside another.
'bees' becomes 'bb' (the letter B written twice).
'air' anagrammed gives 'rai'.
'rai' going around 'bb' is 'RABBI'.
'in' acts as a link.
(Other definitions for rabbi that I've seen before include "Religious person" , "Religious scholar" , "endless waffle" , "Blue" , "Sacks, for example" .)
