/adʌɪˈnamɪk/, U.S.

/ˌeɪdaɪˈnæmɪk/,

/ædaɪˈnæmɪk/

Origin: Formed within English, by derivation. Etymons: a- prefix⁶, dynamic adj.

Etymology: < a- prefix⁶ + dynamic adj. In sense 1a after French adynamique ( P. Pinel Nosographie philosophique (1797) I. 7). Compare earlier adynamia n. Compare also slightly earlier adynamical adj.

1. Medicine.

a. Originally: resulting in or characterized by weakness or debility (cf. adynamia n.); spec. designating fevers, esp. typhus and typhoid, which have a marked debilitating effect (now rare). In later use: spec. exhibiting, characterized by, or resulting from reduced or absent muscular contraction.
