The story

Prendre is derived from Latin prēndere, present active infinitive of prēndō, a variant of prehendō (‘to catch, lay hold of; to grasp; to grab, snatch; to seize, take’), ultimately from Proto-Indo-European *gʰed- (‘to find; to hold; to seize, take’). The intrusive g in the English word was modelled after words like deign and reign.
