Tvirtini

Tvirtini is a form of the Lithuanian verb tvirtinti, specifically the second-person singular present indicative. In English, it corresponds to “you strengthen,” “you fasten,” or “you confirm,” depending on context. It is used when addressing someone directly to indicate that they are performing the action of making something secure, firm, or verified.

In everyday and technical usage, tvirtinti covers a range of meanings from physical fastening to establishing confirmation. Examples include: Tu tvirtini plokštę, meaning “You fasten the plate.” Ji tvirtina savo nuomonę, meaning “She confirms/affirms her opinion.” Mūsų saugos planas tvirtina, kad konstrukcija atlaikys apkrovą, meaning “Our safety plan asserts that the structure will withstand the load.” The sense can shift with context from securing objects to validating statements or conclusions.

Etymologically, tvirtini derives from the Lithuanian root tvirt-, which conveys the idea of firmness or solidity. The verb tvirtinti forms part of related words such as tvirtinimas (fastening, reinforcement) and tvirtinimas/confirmations in more formal language. The form tvirtini is primarily encountered in Lithuanian grammar and usage, rather than as a standalone lexical entry in many dictionaries.
