What does documentary mean?
A documentary is a work of film, television, or radio whose purpose is to record and present reality rather than to invent fiction. Documentaries explore real people, places, events, and issues, typically through interviews, archival footage, and narration, with the goal of informing or persuading an audience. The word also functions as an adjective meaning factual and unembellished: a 'documentary style' of filmmaking aims for authenticity, while in legal language 'documentary evidence' means proof supplied by written records rather than testimony. Coined from 'document', the term gained its modern sense in the early twentieth century as cinema matured beyond entertainment into a tool of reportage and education. Today documentaries are a respected genre spanning nature films, historical accounts, true-crime series, and investigative journalism, valued both as sources of knowledge and as a creative medium in which fact is shaped — carefully or controversially — into compelling storytelling.
A film, television, or radio programme that provides a factual report on a particular subject.
"They watched a documentary about deep-sea exploration last night."
Plural: documentaries. Often preceded by a topic phrase, e.g. 'a documentary about/on climate change'.
Presenting facts objectively and realistically, without fictional elements; or relating to documents.
"The photographer's documentary style captured everyday street life with striking honesty."
In legal usage, 'documentary' almost always appears in the fixed phrase 'documentary evidence'.
Standard English plural, replacing '-y' with '-ies'. Applies only to the noun sense.
"The festival showcased over fifty documentaries from around the world."
The word 'documentary' was popularised in the 1920s by Scottish filmmaker John Grierson, who described it as the 'creative treatment of actuality' — turning fact itself into an art form.

Etymology of documentary
Documentary derives from 'document', which entered English via French from Latin 'documentum', meaning a lesson, proof, or instruction, formed from 'docere', to teach. The adjective originally meant simply 'relating to documents' before being applied to film. Its modern cinematic sense was established in the 1920s, largely through Scottish filmmaker John Grierson's influential writing on non-fiction film.
How documentary is actually used
As a noun, 'documentary' is informal enough for everyday speech but neutral in register. In British English it is sometimes shortened informally to 'doc'. The adjective sense relating to documents is most common in legal contexts ('documentary evidence').
