Tramples relative underfoot? (7)
I believe the answer is:
stepson
I believe this clue is a triple definition!
'tramples' is the first definition.
(I've seen this before)
'relative' is the second definition.
(stepson is a kind of relative)
'underfoot?' is the third definition.
(I've seen this before)
(Other definitions for stepson that I've seen before include "younger member of family" , "partner's sprog" , "could be issue for partner" , "No pests (anag)" , "underfoot?" .)
