You or I, say (7)
I believe the answer is:
pronoun
This clue is a double definition.
'you' is the first definition.
('you' is a pronoun)
'i say' is the second definition.
(I've seen this before)
(Other definitions for pronoun that I've seen before include ""She" or "him", for example" , "Word like I or she" , "Substitute for a noun" , "Category of word" , "He is one" .)
