seminayjnych

Seminayjnych appears not to be a standard Polish word found in reputable dictionaries. It is most likely a misspelling or nonstandard variant of related adjectives such as seminarny or seminaryjny, which derive from the noun seminarium (seminar, seminary). In Polish, adjectives agree with the noun they modify, and the expected correct forms include seminarny (adjective), seminaryjny (another common variant), and their inflected forms such as seminarnych or seminaryjnych in the genitive plural.

The root sense of these adjectives is "pertaining to a seminar or to a seminary." Seminarny is typically used for seminar-related contexts (for example, courses or activities organized as seminars), while seminaryjny is used for things associated with a seminary as an institution (for example, seminaryjny budynek, seminaryjne instytucje). The genitive plural forms are seminarnych and seminaryjnych, respectively.

Usage notes and typical phrases help clarify meaning. For educational contexts, one frequently encounters phrases like koszty zajęć seminarnych (costs of seminar courses) or instytucje seminaryjne (seminary institutions). If the intended term was indeed “seminayjnych,” it would generally be viewed as nonstandard; in formal writing, the standard forms seminarnych or seminaryjnych should be used depending on the exact meaning.

If you meant a different term or a proper noun, additional context would help determine a precise article. See also: seminar, seminarian, seminary, seminarial.
