English-French-Persian

1) To grow or sprout as a plant by nutriment imbibed through roots and leaves.
2) To lead a passive life without much physical, mental, or social activity.

Ultimately from L. vegetatus, p.p. of vegetare "to enliven, to animate," from vegetus "vigorous, enlivened, active," from vegere "to be alive, active;" akin to Skt. vaja- "force, strength;" PIE root *weg- "to be strong, be lively."

Giyâhidan, infinitive forum giyâh, → plant.
