preobtained

Preobtained is an adjective formed from the prefix pre- meaning before, combined with obtained, the past participle of obtain. It describes something that has already been obtained prior to a specific event, decision, or date. The term is infrequent in standard dictionaries and is more common in technical or multidisciplinary contexts where explicit timing of acquisition matters.

In practice, preobtained data, preobtained consent, or preobtained materials are used to indicate that items were acquired beforehand to streamline processes, reduce risk, or satisfy prerequisites. For example, a study might rely on preobtained datasets collected in a pilot phase, or an insurer might require preobtained information to expedite a claim. The hyphenated form pre-obtained is also seen in some texts.

Because preobtained is not widely standardized, it can be ambiguous; writers should define the term when introducing it and ensure consistent usage. It is distinct from terms like preexisting or previously obtained, though contexts can overlap.

Related terms include preexisting, beforehand, and preacquired, though each carries its own nuance of timing and scope.
