Early settler finally relaxed and fished (6)
I believe the answer is:
angled
'fished' is the definition.
(angling is a kind of fishing)
'early settler finally relaxed' is the wordplay.
'early settler' becomes 'Angle' (European settler in England).
'finally' suggests the final letters.
The final letter of 'relaxed' is 'd'.
'angle'+'d'='ANGLED'
'and' is the link.
(Other definitions for angled that I've seen before include "Glenda (anag.)" , "Fished with rod and line" , "Cornered" , "Crooked; biased" , "Slanted" .)
