Headin

Headin is a term that does not have a widely accepted, fixed meaning in English. In most references, headin appears as a misspelling or truncation of the word heading, which designates a title, subtitle, or section label in text, web pages, and document formatting. Because of its lack of standard definition, headin also appears in informal writing, notes, or digital transcripts where the final 'g' is dropped or where line breaks interrupt the word.

In computing and publishing contexts, there is no recognized technical concept named headin. When it does occur, it is usually a typographical error rather than a defined term. The phrase may also appear as a rare or mistaken proper noun: as a place name, surname, or brand, it is not widely documented in reference works and would be highly contextual.

Etymologically, headin is most plausibly a shortened form of heading, or a transliteration from a language where the ending is not pronounced. In absence of reliable context, readers should treat headin as an error or as a placeholder that stands for heading in text.
