Letter I see as truly quoted (3)
I believe the answer is:
sic
'letter i see as truly quoted' is the definition.
I can't judge whether this defines the answer.
'letter i see' is the wordplay.
'letter' becomes 's' ().
'see' becomes 'C' (the word for the letter, according to Chambers).
's'+'i'+'c'='SIC'
Can you help me to learn more?
(Other definitions for sic that I've seen before include "Thus among musicians" , "'Thus, in printing (3)'" , "Quoted exactly as in the original; so" , "As it stands, in printing" , "Thus in Corsica" .)
