I
“If then your I [yes] agreement want,
I to your I [yes] must answer, ‘No.ʹ
Therefore leave off your spelling plea,
And let your I [yes] be I per se.”
i.e. let your yes be yes decidedly.
⁂ Many other letters are similarly used; as, A per se. (See A-Per-Se.) Thus in Restituta Eliza is called “The E per se of all that ere hath been.” So again, “O,” signifies a crier, from “O yes! O yes!” We have “Villanies descovered by … the help of a new crier, called O per se [i.e. superior to his predecessors].” 1666.
Shakespeare, in Troilus and Cressida, i. 2, even uses the phrase “a very man per se” = A 1.
