pliant

The word "pliant" entered English in the 14th century from the Old French pliant, the present participle of plier ("to bend"). This Old French term descended directly from the Latin plicāre ("to fold, bend, or coil"). The core semantic thread from the Proto-Indo-European root plek- ("to plait, to weave") through Latin and into modern English is one of flexibility and the capacity to be folded or shaped. The literal sense of physical flexibility evolved naturally into the abstract meaning of being easily influenced or adaptable in character, completing the journey from a concrete physical action to a descriptive psychological trait.

Structure: pli (to bend) + ant (adjective-forming suffix) The morpheme "pli" originates from the Latin verb plicāre, meaning "to fold, to bend." The suffix "-ant" comes from the Latin present participle suffix -antem, which, when adopted into English, forms adjectives meaning "performing the action of" or "characterized by."
