What does dep mean?
"Dep" is not a word in its own right but a widely used abbreviation that stands in for several longer terms, most often "departure." Travelers encounter it constantly in airport boards, train timetables, and booking confirmations, where a "dep" column lists leaving times opposite arrivals. In workplace and administrative contexts it may instead shorten "deputy" (as in dep director), "deposit," or "department." Because it carries no fixed meaning independent of context, readers must infer the intended expansion from the setting. It belongs to informal and technical written registers — signs, schedules, forms, notes — and is rarely spoken aloud as "dep." For general prose, style guides favor spelling out the full word, reserving the abbreviation for space-constrained formats where its meaning is unmistakable.

Etymology of dep
"Dep" arose simply as a clipping — a shortened written form — of longer English words such as "departure," "deputy," "deposit," and "department." As a mere abbreviation, it has no independent etymology, first language of origin, or cognates of its own; any history it has is borrowed entirely from the full words it represents.
How dep is actually used
Strictly an abbreviation rather than a standalone word; almost always found in writing — timetables, schedules, job titles, forms — rather than in speech. Its meaning depends heavily on context, so it should be avoided in formal prose where the full word can be used.
Easily confused with dep
"Deep" is a full adjective meaning far down or intense, while "dep" is only an abbreviation for words like departure or deputy.
