wiadczona

Wiadczona is a feminine form of a past participle in Polish, derived from the verb świadczyć, meaning to bear witness or testify. In standard contemporary Polish, the more common feminine form is typically świadcоna, but wiadczona appears as a historic or dialectal variant and is encountered mainly in older texts, legal archives, or linguistic discussions about Polish inflection. It may also occur as a stylistic or orthographic variant influenced by pronunciation or regional spelling.

Grammatically, wiadczona functions as an adjectival participle: it agrees in gender and number with the noun it modifies. The corresponding masculine form is wiadczony, and the neuter plural is wiadczone. The meaning is that the object or statement has been witnessed or attested by someone, though in practice the variant is far less common than the standard form.

In usage, the term is largely confined to formal or historical contexts and is not a common feature of everyday speech. It can appear in phrases indicating that an item has been evidenced or testified to, for example in documentary or archival language, where a witness statement or testimony is noted as having been provided.

Etymology: the form is related to the verb świadczyć and other witness-related terms in Polish. The spelling wiadczona reflects historical orthography and regional pronunciation, and today it is primarily of linguistic or historic interest rather than a living, widely used word.
