Very entertaining (5)
I believe the answer is:
jolly
This clue might be a double definition.
'very' is the first definition.
(I've seen this before)
'entertaining' is the second definition.
Both the answer and definition are adjectives. Perhaps you can see an association between them that I can't see?
Can you help me to learn more?
(Other definitions for jolly that I've seen before include "Happy, cheerful" , "Mirthful" , "Very - jovial" , "all-expenses-paid trip" , "' - - boating weather' (song)" .)
