the.com/application

means A formal request — often a written form or document — submitted to ask for something like a job, a loan, a place at a school, or permission; also a piece of software you run on a computer or phone.

from From Latin 'applicare,' to attach or join to — built from 'ad-' (to) plus 'plicare' (to fold), the same fold that gives us 'pliable' and 'ply.' The literal sense is something laid against or folded onto another thing, which is why you 'apply' paint to a wall, 'apply' yourself to a task, or 'apply' for a job — all variations on attaching your effort or your request to something. It reached English through Old French in the late Middle Ages; the software sense ('application program,' later clipped to 'app') is a 20th-century borrowing of the same idea: a program applied to a particular use.
