vierittä

Vierittää is a Finnish verb used primarily in formal or technical language to denote the act of verifying, cross-checking, or corroborating information, data, or calculations. The sense is close to tarkistaa or varmistaa but carries the nuance of validating consistency across sources or documents. Because of its formal character, vierittää tends to appear in administrative, legal, research, auditing, or bureaucratic writing rather than in everyday speech.

Usage of vierittää typically involves objects such as statements, figures, data sets, or documents. It is employed in contexts where a process requires external validation or reconciliation between sources. In many texts, the verb signals a specific step in a workflow or a quality-control procedure, and it is often accompanied by descriptors of how the cross-checking is performed or who is responsible.

The term is related to other Finnish verbs for checking and confirming, such as tarkistaa, varmistaa, and verrata. While tarkistaa can cover general checking and accuracy, vierittää emphasizes cross-source verification and consistency across different materials. Grammatically, vierittää behaves as a regular -ttää verb and can appear in various moods, tenses, and voices like other Finnish verbs.
