Spots an insect crawling round the hole (7)
I believe the answer is:
notices
'spots an' is the definition.
'notices' can be an answer for 'spots' (I've seen this before). I am unsure of the 'an' bit.
'insect crawling round the hole' is the wordplay.
I cannot quite see how this works, but
'round' could be 'o' (round can mean a round object) and 'o' is found in the answer.
an anagram of 'insect' is 'ntices' which is present in the left over letters.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for notices that I've seen before include "advertisements" , "Remarks upon publicly displayed informations" , "reviews" , "Pays attention" , "Perceives, sees" .)
