contrastado

Contrastado is a Spanish adjective and the past participle of the verb contrastar. It denotes that something has undergone contrast, in the sense of being compared, checked, or verified against another source, data set, or method. In scientific, journalistic, and formal writing, contrastado commonly means that a claim or result has been corroborated by independent evidence or replication. Common collocations include datos contrastados, resultados contrastados, evidencia contrastada, and criterios contrastados.

Etymology and usage notes: the term derives from contrastar, which traces back to Latin contra- “against” and stare “to stand.” As a participle adjective, it agrees in gender and number (contrastado/contrastada, contrastados/contrastadas). In addition to its data-verification sense, contrastado can appear in medical contexts to describe imaging procedures that use a contrast agent; for instance, an image or a patient may be described as contrastado when contrast material has been administered.

Contexts and nuance: while most common in technical writing, contrastado also appears in legal, academic, and administrative texts to indicate that findings or documents have been checked against standards or corroborating sources. It is not a synonym for unverified or inconclusive; rather, it implies a level of confirmation or cross-checking.
