affectation

the word 'affectation' entered english in the mid-16th century from latin affectation-, from the verb afficere, itself composed of ad- ('to') and facere ('to do, make'). the core latin meaning was 'to apply oneself to, strive after'. this evolved into the sense of 'to assume or put on a manner', reflecting the effort involved in artificial display. the suffix -ation solidifies this action into a noun denoting the resulting state or behavior. thus, the etymological logic moves from the literal act of 'doing to' or 'striving for' a particular manner, to the modern abstract concept of artificial, pretentious behavior.

Structure: affect (to do, to act upon) + ation (noun suffix) affect: from latin affect-, the past-participle stem of afficere meaning 'to do to, act upon, influence'. in this word, it carries the sense of 'to put on a pretense of'. ation: a latin-derived suffix forming nouns of action or state, from -ationem (nominative -atio).
