What does install mean?
Install means to put something into a particular place or position, usually so that it is ready to be used. The word is especially familiar in technical contexts, in which it describes adding software to a device, fitting equipment, or applying a system update. It can also have a formal social meaning: to appoint someone to a role or establish them in a position, as when a committee installs a new chair. In ordinary conversation, install often implies a deliberate action involving placement, setup, or preparation. The related noun installation can refer both to the process of putting something in place and to the thing itself, such as a security installation. Although the verb is common in both British and American English, the spelling instal is also widely used in British English.
To place or fit something into position, or make it ready for use; to put software or a program onto a device; to appoint or establish someone in a role.
"We installed the application and tested it on several devices."
The verb is transitive in its standard uses, though it can also occur intransitively, especially in technical contexts.
The act or process of installing something; an installation.

Install comes from a Latin word meaning “to put in place,” a fitting origin for a term that now means putting software, equipment, and even people into position.

Where does install come from?
Install entered English in the early 17th century through French installer, from Latin installare, meaning “to put in place.” The Latin verb combined the prefix in- with stāre, “to stand.” English later developed related forms such as installation and installer, while the cognate verb instill comes from a separate Latin formation meaning “to drop in” or “impart gradually.” The British spelling instal is a historical variant of install.
