Biting insect not half minor in producing irritations (7)
I believe the answer is:
tickles
'producing irritations' is the definition.
I can't judge whether this defines the answer.
'biting insect not half minor' is the wordplay.
'biting insect' becomes 'tick' (I've seen this before. I am not sure about the 'biting' bit.).
'not half' suggests halving the letters.
'minor' becomes 'lesser' (I've seen this before).
'lesser' with half the letters taken is 'les'.
'tick'+'les'='TICKLES'
'in' is the link.
Can you help me to learn more?
(Other definitions for tickles that I've seen before include "Excites" , "Light touches that cause laughter" , "Soft touches" , "Amuses" .)
