Etymology

Origin of application

First recorded in 1375–1425; late Middle English, from Middle French applicacio(u)n, from Latin applicātiōn- (stem of applicātiō ), equivalent to applicāt(us) “applied” (past participle of the verb applicāre apply ) + -iōn- -ion

Explanation

An application is a request for a job, assistance or admission to a school. Colleges might want you to submit your application by Dec. 1, but they won't let you know if you've been accepted until sometime in April. An application is also a form you fill out for something. If you need a handicapped parking permit, you and your doctor must first fill out an application and then submit it in the town hall. An application is also a computer program designed to perform a task or solve a problem. If you didn't get enough sleep last night, the careful application of makeup can mask the dark circles under your eyes.
