prey: [13] Prey comes via Old French preie from Latin praeda ‘booty’ (from which was derived the verb praedārī ‘plunder’, source of English depredation [15] and predatory [16]). This was a contraction of an earlier praeheda, a noun formed with the prefix prae- ‘before’ from the same base (*hed- ‘seize’, source also of English get) as produced the verb praehendere ‘seize’.

This has been a rich source of English vocabulary, contributing through different channels such a varied assortment as prehensile [18], prison, and prize ‘something seized in war’, not to mention prefixed forms like apprehend. comprehend [14], comprise [15], impregnable [15], reprehensible, reprieve, and surprise. It is also the ancestor of French prendre ‘take’.
