The main parts of speech in English are:
* Nouns: Words that name people, places, things, or ideas (e.g., *dog*, *house*, *love*).
* Pronouns: Words that replace nouns (e.g., *he*, *she*, *it*, *they*).
* Verbs: Words that describe actions, states of being, or occurrences (e.g., *run*, *sleep*, *exist*).
* Adjectives: Words that modify nouns or pronouns (e.g., *big*, *red*, *happy*).
* Adverbs: Words that modify verbs, adjectives, or other adverbs (e.g., *quickly*, *very*, *always*).
* Prepositions: Words that show the relationship between a noun or pronoun and another word in the sentence (e.g., *on*, *in*, *to*, *from*).
* Conjunctions: Words that connect words, phrases, or clauses (e.g., *and*, *but*, *or*, *because*).
* Interjections: Words that express strong emotion (e.g., *Wow*, *Ouch*, *Oh no!*).
To determine the part of speech of a word, you need to consider its role in the sentence. For example:
* "The dog chased the ball." Here, "dog" and "ball" are nouns.
* "She ran quickly." Here, "ran" is a verb and "quickly" is an adverb.
