Adverbs in the Lithuanian language, similar to adverbs in English, modify verbs, adjectives, other adverbs, or entire sentences. They are not declined (i.e., they don’t change forms depending on the case, gender, or number). The main types of adverbs in Lithuanian grammar include manner (kaip?), place (kur?), time (kada?), intensity (kiek?), and reason (kodėl?) adverbs.
