What does expunction mean?
Expunction is a formal noun denoting the act of completely removing or erasing something — most commonly a record, name, or passage from an official document, register, or text. It derives from the Latin verb expungere, literally 'to prick out', referring to the ancient practice of marking unwanted words in a manuscript with dots so they could be deleted. Today the word appears chiefly in legal contexts: courts may grant the expunction of a criminal record or arrest from public databases, effectively treating the event as though it never occurred. Beyond law, it can describe the excision of material from a book or archive. Expunction carries a connotation of thoroughness and finality — what is expunged is erased entirely, not merely hidden — which gives the word a precise, authoritative tone suited to formal writing.

In Texas law, an expunction doesn't just seal your record — it legally permits you to deny the arrest ever happened.

Etymology of expunction
Expunction comes from Latin expunctio, from expungere, meaning 'to prick out' or 'mark with dots for deletion' — formed from ex- ('out') and pungere ('to prick'). Roman scribes marked passages for removal by pricking dots above them. The word entered English in the early 17th century alongside its verb counterpart 'expunge'. It shares its root punctum ('prick, point') with words such as punctuation, punctuate, and puncture, all ultimately tracing back to the same Proto-Indo-European root.
