Don't bore everybody, even if it is annoying (8)
I believe the answer is:
tiresome
'is annoying' is the definition.
(I've seen this before)
'don't bore everybody even if it' is the wordplay.
I cannot quite see how this works, but
'bore' could be 'tire' (I've seen this in another clue) and 'tire' is present in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tiresome that I've seen before include "Annoying, being a nuisance" , "Fatiguing; boring" , "Causing boredom" , "Wearying" , "Rather boring" .)
