Fellow rings daughter to get nutrition (4)
I believe the answer is:
food
'nutrition' is the definition.
(I've seen this before)
'fellow rings daughter' is the wordplay.
'fellow' becomes 'f' (abbreviation - of a society etc.).
'rings' becomes 'oo' (multiple circles).
'daughter' becomes 'd' (genealogical abbreviation).
'f'+'oo'+'d'='FOOD'
'to get' acts as a link.
(Other definitions for food that I've seen before include "Solid nourishment" , "Sustenance" , "course?" , "Things to eat" , "Nutritious substance" .)
