filename

The word 'filename' is a modern English compound, formed by directly combining two native English words. The first element, 'file', has a long history tracing back to the Latin fīlum (thread), which metaphorically evolved to mean a collection of documents strung together for keeping. The second element, 'name', originates from the Proto-Indo-European root h₁nómn̥, fundamental to the concept of identification. In the context of computing, this transparent compound logically denotes the identifying label assigned to a specific collection of digital data, seamlessly extending the ancient concepts of threading documents and giving them an identity into the digital realm.

Structure: file (document) + name (identifier) - file: From Old English fīl (a string or wire for documents), via French fil (thread), from Latin fīlum (thread). In this compound, it functions as a noun denoting a collection of stored data. - name: From Old English nama, noma, from Proto-Germanic namô, from Proto-Indo-European h₁nómn̥. In this compound, it functions as a noun meaning a word by which something is known.
