Holy man left in endless poverty is to stay snug (6)
I believe the answer is:
'stay snug' is the definition.
'nestle' can be an answer for 'snug' (thesaurus). I am not sure about the 'stay' bit.
'holy man left in endless poverty' is the wordplay.
'holy man' becomes 'st'.
'left' becomes 'l' (common abbreviation**).
'in' is an insertion indicator.
'endless' means to remove the last letter.
'poverty' becomes 'need' (I've seen this before).
'need' with its last letter removed is 'nee'.
'stl' going within 'nee' is 'NESTLE'.
'is to' acts as a link.
Can you help me to learn more?
(Other definitions for nestle that I've seen before include "Chocolate maker" , "Lie snugly (in a place)" , "Press close and snugly" , "Lie in cosily" , "Cuddle or snuggle up" .)
