Experiences of son supporting discrimination (6)
I believe the answer is:
tastes
'experiences' is the definition.
(taste is a kind of experience)
'son supporting discrimination' is the wordplay.
'son' becomes 's'.
'supporting' means one lot of letters go next to another (in a down clue, some letters go below others).
'discrimination' becomes 'taste' (taste is a kind of discrimination).
's' after 'taste' is 'TASTES'.
'of' acts as a link.
(Other definitions for tastes that I've seen before include "Penchants or savours" , "'Preferences, predilections (6)'" , "Savours or sensibilities" , "Relishes or penchants" , "Partakes of" .)
