Some years supporting males in household (6)
I believe the answer is:
menage
'household' is the definition.
(eg menage a trois, literally a household of three)
'some years supporting males' is the wordplay.
'some years' becomes 'age' (period of many years).
'supporting' is a charade indicator (letters next to each other) (in a down clue, some letters go below others).
'males' becomes 'men' (man is a kind of male).
'age' put after 'men' is 'MENAGE'.
'in' is the link.
(Other definitions for menage that I've seen before include "A household, sometimes naughtily a trois" , "a household, may be naughtily a trois" , "Social unit living together" , "Persons of household" , "Members of a household" .)
