Odkyslenej

Odkyslenej is an informal, dialectal adjective used in Czech and some Slovak speech to describe something that has become soured or acidified. It is most often applied to foods or beverages that have undergone fermentation or spoilage, where the result is a sour taste or smell. The standard, non-colloquial equivalents would be odkyselený (masculine), odkyselená (feminine), or odkyselené (neuter).

Etymology and grammar: the word is derived from kyselý, meaning sour, with the prefix od- and the participial ending -ený, producing a participial adjective. In casual speech the form odkyslenej is commonly used for masculine singular predicative positions, as in “To mléko je odkyslenej” or “Ten sýr je odkyslenej.” The feminine and neuter forms in casual speech align with odkyselená and odkyselené, respectively, though more formal writing would prefer the standard forms.

Usage and nuance: odkyslenej is primarily a spoken or informal written term. It conveys immediacy and a rustic or everyday tone, and is frequently heard in kitchens, markets, cooking discussions, or humorous contexts. It can describe dairy products like milk or yogurt that have soured, but may also be used metaphorically to describe a mood or situation that has turned sour.

Limitations: this term is not part of formal dictionaries and is considered slang or regional. In formal writing, the standard odkyselený/odkyselená/odkyselené should be used. See also kyselý, odkyselit, odkyselení.
