As the Supreme Court of Michigan wrote, in Walden:

"[A]ffiant and deponent may be said to be synonymous."

Burrill defined a deponent as follows:

"One who deposes (that is, testifies or makes oath in writing) to the truth of certain facts; one who gives, under oath, testimony which is reduced to writing; one who makes oath to a written statement. The party making an affidavit is generally so called."
