Sense: noun/1
"Use" is the most general of the three — it covers any act of employing something for a purpose, whether concrete ("the use of a tool") or abstract ("the use of logic"). "Application" suggests putting a principle, rule, or method into practice in a specific situation ("the application of this theory to real classrooms"). "Employment" is more formal and often implies selecting a particular method or tool as a means to an end ("the employment of advanced encryption"). Unlike "usage," none of these words is tied specifically to language. In language contexts, "usage" carries a social or conventional dimension — it is about how a community actually speaks or writes, not just the act of using words.

Etymology
From Old French 'usage', meaning 'custom, practice, use', which came from Latin 'usus' ('use, practice, custom'), derived from the verb 'uti' ('to use'). The word entered Middle English around the 13th century, carrying both the idea of habitual practice and the act of using something.
