The Greek roots

ἀ-
a-
without, not
+
κίνησις
kínēsis
movement

Literally: no movement

The story of the word

It is not weakness. A patient with akinesia has the strength to walk and cannot start walking, and may unfreeze the instant a stripe is taped across the floor to step over. Kínēsis is the ordinary Greek noun for motion, and it built kinetic energy, cinema and the whole dyskinesia family that names movement going wrong from the other direction.
