Every word in a sentence has a job. That job is called its part of speech. There are 8 parts of speech in English.

1. Noun — names a person, place, thing, or idea.
   Examples: dog, London, freedom, teacher
2. Verb — expresses an action or state of being.
   Examples: run, is, think, was
3. Adjective — describes or modifies a noun.
   Examples: red, tall, happy, three
4. Adverb — describes a verb, adjective, or another adverb. Often ends in -ly.
   Examples: quickly, very, here, yesterday
5. Pronoun — replaces a noun to avoid repetition.
   Examples: he, she, it, they, we
6. Preposition — shows the relationship between a noun and another word.
   Examples: in, on, at, between, under
7. Conjunction — connects words, phrases, or clauses.
   Examples: and, but, or, because, although
8. Interjection — expresses emotion. Usually followed by an exclamation mark.
   Examples: Wow!, Oh!, Oops!, Hey!

Tip: The same word can be different parts of speech depending on how it is used in the sentence.

Example: "I need a light jacket." (adjective) vs. "Please light the candle." (verb)
