Explanation:
Adverbs are words that have the power to modify other grammatical classes, specifying them in relation to time, place and mode. In a few words we can say that adverb is an invariable word that indicates the circumstances where the verbal action was established.
Subject is the individual who is suffering or promoting the action of the verb.
Verb is the word that indicates an action, process, state or phenomenon of nature.
Article is the word that precedes the noun, identifying it in relation to the number.
Prepositions are words that make connections between sentences.
