Morphology

vacillant = vacillate (semi-transparent) = vacillate + ant

The adjective is directly formed from the verb 'vacillate' with -ant, but the French/Latinate adjectival suffix and the rare usage make the formation less immediately obvious to many learners.

Etymology

Vacillant comes from the Latin verb vacillare, which means 'to sway' or 'to wobble'. You can see the same root in vacillate, so vacillant describes a person or plan that 'wavers' and cannot decide.
