Etymology

the word 'exposure' entered english in the early 17th century from the latin verb 'exponere', meaning "to set forth, explain, or expose". this latin source is a compound of the prefix 'ex-' (out) and 'ponere' (to place). the literal sense of "placing out" evolved from the physical act of leaving something unprotected in the open to the more abstract meanings of revealing information or subjecting someone to an influence. the modern english term retains this core logic of being "put out" from a state of protection or concealment, whether referring to a person exposed to the elements, a secret exposed to the public, or film exposed to light.

Analysis

Structure: ex (out) + pos (to place) + ure (noun suffix) - ex: from latin, a prefix meaning "out, out of, from, forth". - pos: from latin root 'ponere' (to place, put), appearing here in a variant spelling 'pos'. - ure: from latin suffix '-ura', denoting an action, process, or result.

Examples

the newspaper's exposure of the corruption scandal led to several resignations.

for a good night photograph, you need a longer exposure time.
