What does documentation mean?
Documentation refers both to the process of recording information systematically and to the resulting collection of documents — manuals, certificates, reports, and records — that serve as evidence or guidance. The word carries a formal, professional tone: one speaks of supporting documentation for a loan application, official documentation at a border crossing, or technical documentation accompanying software. In everyday modern usage it has become especially prominent in technology, where well-maintained documentation can determine whether a product or programming library is usable at all. Derived from the Latin documentum, meaning a lesson or proof, from docere ('to teach'), the term retains an implicit promise: that what is documented will instruct and inform. Its ubiquity in bureaucracy and software alike makes it an essential word for describing how knowledge is preserved and communicated.
The material — such as manuals, certificates, or records — that serves as evidence or official information.
"Customs officers asked to see her travel documentation."
Often used with modifiers like 'supporting,' 'official,' or 'identity.'
The act or practice of documenting something; systematic recording of information.
"Careful documentation of the experiment allowed other researchers to replicate it."
Documentation is an uncountable (mass) noun in English and has no plural form; quantity is expressed with phrases such as 'pieces of documentation' or 'sets of documentation.'
"She gathered several pieces of documentation for the visa application."
Every time a developer sighs 'the docs are useless,' they're invoking a word whose Latin root literally means 'to teach' — documentation was always meant to be the teacher.

Etymology of documentation
Documentation derives from the Latin documentum, meaning 'lesson' or 'proof,' formed from docere, 'to teach.' The verb 'document' entered English in the early 17th century, and 'documentation' followed as its noun of action, first attested around the 18th–19th centuries. It shares this Latin root with words such as documentary, docent, and doctrine.
How documentation is actually used
