pliable (adj.)

late 14c., "easy to be bent, readily yielding to force or pressure without rupture," from Old French ploiable "flexible, bendable," from plier "to bend," from Latin plicare "to fold, lay" (from PIE root *plek- "to plait"). The figurative sense of "flexible in disposition, readily yielding to influence or argument" is by late 15c. Related: Pliably, pliability.
