It's tiresome for a bee to go round and round. (6)
I believe the answer is:
boring
'it's tiresome' is the definition.
(synonyms)
'bee to go round and round' is the wordplay.
'bee' becomes 'b'.
'to' says to put letters next to each other.
'go round' becomes 'ring' (synonyms. I am not sure about the 'go' bit.).
'and' is a charade indicator (letters next to each other).
'round' becomes 'o' (round can mean a round object).
'ring' put after 'o' is 'oring'.
'b' put next to 'oring' is 'BORING'.
'for a' acts as a link.
Can you help me to learn more?
(Other definitions for boring that I've seen before include "Tedious, of no interest" , "Dull and repetitive, a turn-off" , "Drilling can be tedious" , "flat" , "Tedious and tiring" .)
