kúszás

Köszi is a colloquial Hungarian interjection. It is a shortened and informal version of the word "köszönöm," which means "thank you" in Hungarian. The word "köszönöm" itself derives from "köszön," meaning "to thank." "Köszi" is widely used in everyday casual conversation among friends, family, and acquaintances. It is considered a more relaxed and familiar way to express gratitude compared to the more formal "köszönöm" or "köszönjük" (thank you, plural). Its usage is common in spoken Hungarian and increasingly appears in informal written communication such as text messages and social media. While informal, "köszi" is generally understood and accepted in most everyday situations where a casual expression of thanks is appropriate. Using "köszi" in very formal settings, such as addressing a distinguished elder or in official correspondence, might be considered impolite.
