What does doc mean?
"Doc" is a clipped, informal form of "doctor," used chiefly as a friendly or colloquial way of referring to a physician. Its tone is warm and familiar — patients might say "the doc fixed me right up" — and addressing someone as "doc" can carry a breezy, sometimes slightly humorous flavor rather than formal respect. A second, distinct sense has grown out of modern technology: "doc" serves as a common abbreviation for "document," especially a computer file such as a Word document (.doc), making phrases like "send me the doc" everyday speech in offices and online. The word belongs to the same Latin family as "doctor" (from docere, "to teach"), which also gave English words like "doctrine" and "document." Compact, versatile, and instantly recognizable, "doc" shows how English freely shortens long professional titles into approachable, conversational terms.
An informal term for a doctor, especially a physician.

A document, especially a computer file.
"Save the doc as a PDF before sharing it."
Common in workplace and technical speech; the .doc filename extension popularized this sense.
The plural applies naturally to both senses: multiple physicians or multiple documents.
"All the docs in the practice were booked solid that week."
It took just three letters to turn 'doctor' into one of the friendliest words in English — and computers borrowed it for documents too.

Etymology of doc
"Doc" arose in the nineteenth century as a natural spoken shortening of "doctor," itself from the Latin docere, meaning "to teach" — a reminder that the earliest doctors were teachers of their discipline. The same Latin root produced related English words including "doctrine," "document," and "docent." In the late twentieth century, "doc" was independently adopted by the computing world as an abbreviation for "document," giving the short form a second life alongside its medical one.
