IPA: /ˌeɪ.dɪˈnæm.ɪk/
KK: /ædɪˈnæmɪk/
Describing something that lacks energy, strength, or the ability to move or function effectively.
The patient was diagnosed with an adynamic condition that left him feeling weak and fatigued.
Adynamic → It is formed from "a-" (meaning without) and "dynamic" (from Greek "dynamikos", meaning power or force). The word describes a state of being without power or energy.
Think of 'a-' meaning without, and 'dynamic' relating to power — so adynamic means lacking power or energy.
