I, Adam? (5,6)
I believe the answer is:
first person
I believe this is a double definition.
'i' is the first definition.
(I've seen this before)
'adam?' is the second definition.
(I've seen this before)
(Other definitions for first person that I've seen before include "Adam" , "was a faller at the outset" , "royal "we", say" , "I or we (grammar)" , "Rebecca's written in it" .)
