What does appending mean?
Appending is the act of adding something to the end of an existing whole — a line to a document, a record to a file, an item to a list. It is the gerund and present participle of the verb append, which derives from the Latin appendere, meaning 'to hang upon,' a root it shares with words like pendant and pendulum. In modern usage appending is most at home in computing, where programmers and systems constantly append new data to logs, files, arrays, and strings without disturbing the original contents. This makes it a fundamental concept in data handling: unlike overwriting, appending preserves everything already there and simply extends it. Outside technology the word appears in ordinary administrative contexts, such as appending notes to a report or clauses to a contract. Neutral, precise, and practical, appending names one of the simplest yet most essential operations in both language and code.

Etymology of appending
Appending comes from the Latin verb appendere, meaning 'to hang upon' or 'to weigh out,' formed from ad- ('to, toward') plus pendere ('to hang'). English adopted append in the late medieval and early modern period, and its participial form appending developed naturally alongside it. The same Latin root gives English a family of cognates including pendant, pendulum, depend, and suspend, all built around the idea of hanging or being suspended. Its modern prominence owes much to computing, where 'append' became a standard operation name for adding data to the end of a file or structure.

How appending is actually used
Appending is overwhelmingly used in technical and computing contexts today, where it describes adding data to the end of a file, array, or string without altering what came before. In general writing it appears mainly as the gerund or participle form of append; the bare verb 'append' is more common in prose. The word carries no strong connotation — it is neutral and functional.
Easily confused with appending
Prepending adds something to the beginning of a sequence or file, whereas appending adds it to the end.
Attaching joins a separate item (such as a file to an email) as a distinct object, while appending merges content directly into the end of an existing body.
