Gunk from mishandled glue's covering daughter (6)
I believe the answer is:
sludge
'gunk' is the definition.
('sludge' can be a synonym of 'gunk')
'mishandled glue's covering daughter' is the wordplay.
'mishandled' is an anagram indicator.
'covering' means one lot of letters goes inside another.
'daughter' becomes 'd'.
'glues' with letters rearranged gives 'sluge'.
'sluge' placed around 'd' is 'SLUDGE'.
'from' is the link.
(Other definitions for sludge that I've seen before include "Mire - sewage" , "Gloop, gunk, muck" , "Muddy sediment" , "Dirty oil; soft wet mud" , "'Muck, slime (6)'" .)
