Obsolete past tense form putted is attested 14c.-15c. From c. 1300 as "to hurl, cast, propel," especially "to throw with an upward and forward motion of the arm" (Will.

From mid-14c. as "make a declaration, express in speech or writing," hence "express or state (in a particular way)," 1690s, also "propose or place before someone for consideration."

"ruse, deception," 1937, from earlier adjectival meaning "assumed, feigned" (1620s), a figurative extension of the verbal phrase on the notion of putting on costumes or disguises. To put on (v.), of clothes, garments, etc., is by early 15c.; see from put (v.) + on (adv.).

The expression put (someone) on "play a trick on, deceive" (by 1958) seems to be a back-formation from the noun.
