Insect and fish provoking laughter (8)
I believe the answer is:
tickling
'provoking laughter' is the definition.
'tickling' can be an answer for 'provoking' (thesaurus). I'm not sure about the 'laughter' bit.
'insect and fish' is the wordplay.
'insect' becomes 'tick' (I've seen this before).
'and' says to put letters next to each other.
'fish' becomes 'ling' (ling is a kind of fish).
'tick'+'ling'='TICKLING'
Can you help me to learn more?
(Other definitions for tickling that I've seen before include "Action by angler" , "Touching lightly to cause laughter" , "Catching (trout) by rubbing with the hand" .)
