Component in dinner I get possibly (10)
I believe the answer is:
ingredient
'component' is the definition.
(I know that component can be written as ingredient)
'dinner i get possibly' is the wordplay.
'possibly' indicates anagramming the letters.
'dinner'+'i'+'get'='dinneriget'
'dinneriget' anagrammed gives 'INGREDIENT'.
'in' is the link.
(Other definitions for ingredient that I've seen before include "Component element" , "bit of meal?" , "Something used in a recipe" , "One of the things" , "Constituent" .)
