flex
UK: /flɛks/ | US: /flɛks/
v. to bend or contract a muscle or body part
v. to show off one's skills, strength, or possessions
n. the action of bending or the state of being bent
The word "flex" originates from the Latin verb flectere, which means "to bend." It entered English in the 16th century, initially used in scientific and anatomical contexts to describe the bending of muscles or joints. Over time, it evolved into colloquial usage, particularly in the 20th century, to metaphorically "bend" one's abilities or possessions—hence the slang meaning of showing off. The simplicity of the root makes it easy to remember and apply in various contexts.
