a category to which a word is assigned in accordance with its syntactic functions. In English the main parts of speech are noun, pronoun, adjective, determiner, verb, adverb, preposition, conjunction, and interjection.
9. NOUNS
a word (other than a pronoun) used to identify any of a class
of people, places, or things ( common noun ), or to name a
particular one of these ( proper noun ).
11. ADVERB
AN ADVERB CAN MODIFY A VERB, AN ADJECTIVE,
ANOTHER ADVERB, A PHRASE, OR A CLAUSE. AN
ADVERB INDICATES MANNER, TIME, PLACE, CAUSE
OR DEGREE AND ANSWER QUESTIONS SUCH AS
“HOW”, “WHERE”, “WHEN”, “HOW MUCH”.
12. PRONOUNS
a word that can function as a noun phrase used by itself and that refers either to the participants
in the discourse (e.g. I, you ) or to someone or something mentioned elsewhere in the discourse
(e.g. she, it, this ).
13. PREPOSITION
A preposition is a word used to link nouns, pronouns, or phrases to other words within a
sentence. Prepositions are usually short words, and they are normally placed directly in front
of nouns. In some cases, you’ll find prepositions in front of gerund verbs.
