33.1 Adverbs in Greek function much as they do in English; namely, they provide additional information about a verb, adjective, or other adverb. Most often, they indicate manner, time, intensity, quantity, or place. In this lesson, we discuss adverbs that are formed from adjectives.
The most common ending for an adverb is –ως. This ending corresponds almost exactly to the –ly ending in English. Adverbs do not decline.
To form this type of adverb, start with the MASCULINE GENITIVE PLURAL of the ADJECTIVE and substitute –ς for the final –ν (S 343, G 229). (Τhe adverb does not, in fact, derive from the genitive plural, but this method provides a convenient way to determine the form of the adverb.) The ACCENT remains as it was on the genitive plural.
