Plural of documentation; multiple sets of documents, records, or the processes of creating and maintaining records.
From documentation (document + the suffix -ation, meaning 'the process of') plus the plural -s. Documentation itself emerged in English by the 1600s.
In software development, good documentations can be worth millions because poor documentation causes bugs, confusion, and project failures—companies that treat documentation as afterthought instead of core work always regret it.
