Tool, it turns out, captivates blokes (10)
I believe the answer is:
instrument
'tool' is the definition.
(synonyms)
'it turns out captivates blokes' is the wordplay.
I cannot quite understand how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found in the answer.
'blokes' could be 'men' (I've seen this in other clues) and 'men' is located in the answer.
an anagram of 'turns' is 'nsrut' which is present in the remaining letters.
A single letter 'i' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for instrument that I've seen before include "Word puzzle" , "Joanna, perhaps" , "What's needed for 1 [MUSICIAN]" , "Means of precision work (or music-making)" , "legal document" .)
