An abbreviation commonly used in computing for 'reset' or in documentation systems for 'reStructuredText'.
Modern acronym from either 'reset' (from Latin 're-' meaning 'again' and Old English 'settan') or 'reStructuredText' (a markup language created in 2002). Both usages emerged from computing contexts in the late 20th century.
RST demonstrates how computing has created its own linguistic ecosystem of abbreviations that can have multiple meanings depending on context. The ambiguity actually works because context usually makes the intended meaning clear to practitioners.
