During test, question playing something fine and catchy? (8,3)
I believe the answer is:
mosquito net
'something fine and catchy?' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'during test question playing' is the wordplay.
'during' means one lot of letters goes inside another.
'test' becomes 'MOT' (MOT test).
'playing' is an anagram indicator.
'question' anagrammed gives 'squitone'.
'mot' going around 'squitone' is 'MOSQUITO-NET'.
Can you help me to learn more?
(Other definitions for mosquito net that I've seen before include "Screen used to keep off insects" , "a fine thing to hang" , "way to limit airborne disease" , "Protection against disease" , "Device for avoiding fever" .)
