changed

the verb 'change' entered english in the 13th century from old french 'changier', meaning 'to alter or exchange'. old french derived it from late latin 'cambiare', which itself came from latin 'cambire', a term of gaulish origin meaning 'to exchange or barter'. the core concept of substitution and alteration has remained remarkably consistent from its celtic-latin roots through its french transmission into english. the '-ed' suffix, used to form the past tense and past participle, is a common germanic inflectional ending, and when attached to 'change', it creates the adjective 'changed', describing a state resulting from the action of alteration.

the word 'changed' is a simplex form, being the past tense and past participle of the verb 'change'. it is not productively segmented into smaller, meaningful morphemes in modern english.
