Fair start to day -- is most of Bury relaxed? (13)
I believe the answer is:
disinterested
'fair' is the definition.
('disinterested' can be similar in meaning to 'fair')
'start to day is most of bury relaxed?' is the wordplay.
'start to' indicates taking the first letters.
'most of' means to remove the last letter.
'bury' becomes 'inter' (I've seen this before).
'relaxed?' becomes 'rested' (I've seen this before**).
The first letter of 'day' is 'd'.
'inter' with its final letter removed is 'inte'.
'd'+'is'+'inte'+'rested'='DISINTERESTED'
(Other definitions for disinterested that I've seen before include "Feeling no concern" , "Desire dentist (anag) - free from partiality" , "Impartial" , "Not expecting any profit" , "Objective - uninvolved" .)
