Those home ones that can hurt in extremes of tediousness? (6)
I believe the answer is:
truths
'those home ones' is the definition.
I can't tell whether this defines the answer.
'can hurt in extremes of tediousness?' is the wordplay.
'can' is an anagram indicator (I've seen 'canned' mean this (canned can mean drunk)).
'in' is an insertion indicator.
'extremes of' suggests removing the centre (only the letters at the extremes of the word).
'tediousness' with its centre removed is 'ts'.
'hurt' with letters rearranged gives 'ruth'.
'ruth' put within 'ts' is 'TRUTHS'.
'that' acts as a link.
Can you help me to learn more?
(Another definition for truths that I've seen is " Verities".)
