okyseluj

Okyseluj is a Czech verb in the imperative mood meaning “acidify!” It is the second-person singular imperative form of the imperfective verb okyselovat, used to instruct someone to add acid to a substance in order to lower its pH.

Etymology and scope: The verb is built from the noun kysel (acid) with the productive suffix -ovat, creating a verb that denotes a chemical or technical action. It is primarily found in technical, laboratory, culinary, or agricultural contexts and is more common in written instructions than in everyday speech.

Aspect and related forms: Okyselovat is imperfective; its perfective counterpart is okyselit, which expresses a completed acidification. The imperative form okyseluj explicitly commands a single act or a short sequence of actions. Example: Okyseluj roztok octovou kyselinou, dokud roztok nedosáhne požadovaného pH.

Usage notes: In common speech, speakers may prefer neutral verbs such as acidifikovat or okyselit, depending on context. Okyseluj is most likely to appear in manuals, recipes, or lab protocols, and may sound technical if used outside those contexts.
