classes.
NOUNS
Annotations:
These name a person, a place, a thing, an idea, a living creature, a quality, or an action.
PRONOUNS
Annotations:
They are used instead of a noun, to avoid repeating the noun.
VERBS
Annotations:
They describe an action (doing something) or a state (being something).
ADJECTIVES
Annotations:
They describe a noun. They tell you something about the noun.
ARTICLES
Annotations:
They are used to introduce a noun.
ADVERBS
Annotations:
These words usually describe a verb. They tell you how something is done. They may also tell you when or where something happened.
PREPOSITIONS
Annotations:
They usually come before a noun, pronoun or noun phrase. They join the noun to some other parts of the sentence.
CONJUNCTIONS
Annotations:

INTERJECTIONS
