What does dev mean?
"Dev" is an informal English noun that arose as a clipped form of "developer" and now serves two closely related purposes in the technology world. Most often it denotes a software developer — the person who writes, tests, and maintains code — as in phrases like "our dev team" or "the devs shipped the update overnight." It also functions as shorthand for development itself, particularly the stage or environment where software is built and debugged before being released, as in a "dev server" or moving a feature "from dev to production." The term carries a casual, insider tone characteristic of startup and open-source culture, yet it has become so widespread that it appears in job titles, conference names, and mainstream journalism about the tech industry. Its brevity reflects the fast-paced, jargon-heavy register of modern software engineering, where efficiency of expression is prized.
(informal) A software developer.
"Every dev on the team uses a different editor."
Common as both singular and plural ("devs") in workplace and community contexts.
(informal, uncountable) Software development, or the development environment/stage in which software is built and tested prior to release.
"The feature works fine in dev but breaks in staging."
Regular plural, used when referring to multiple developers. The "development/environment" sense is uncountable and does not take a plural.
"The conference drew over two thousand devs from around the world."
"Dev" went from office shorthand to a job title millions of people put on their résumés — no other tech slang has been so thoroughly legitimized.

Etymology of dev
"Dev" is a twentieth-century clipping of "developer" and "development," formed by the common English process of trimming a longer word to its stressed first syllable (compare "prof" for professor and "admin" for administrator). Its underlying root traces back through "develop" to French "développer," ultimately from Latin roots meaning to unwrap or unfold. The clipped form gained currency with the rise of the software industry in the late twentieth century and spread rapidly through computing culture worldwide.

How dev is actually used
Strictly informal and almost entirely confined to computing and tech-industry contexts. As a noun for a person it is fully accepted even in semi-formal tech writing; as shorthand for "development" or a development environment it appears mostly in speech, documentation, and internal communications rather than polished prose.
