Parts of speech are the basic building blocks of English grammar. They show how words function in a sentence. Nouns are naming words, like dog or school. Pronouns replace nouns, such as he or they. Verbs show action or state, like run or is. Adjectives describe nouns, for example beautiful or tall. Adverbs add meaning to verbs and adjectives, such as quickly or very. Prepositions show relationships, like in or on. Conjunctions join words or sentences, such as and or but, while interjections express sudden feelings, like wow or oh. Together, these parts of speech help us form clear and meaningful sentences.
