End life in Irish state, it's neater (6)
I believe the answer is:
tidier
'neater' is the definition.
('tidy' can be similar in meaning to 'neat')
'end life in irish state it's' is the wordplay.
I cannot quite see how this works, but
'end' could be 'die' and 'die' is present in the answer.
'irish' could be 'ir' (abbreviation) and 'ir' is found within the leftover letters.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tidier that I've seen before include "not so disorderly" , "more organised" , "More neat and orderly" , "Trigger" , "straightened up?" .)
