The words we use can be classified under the eight parts of speech: noun, pronoun, verb, adjective, adverb, preposition, conjunction and interjection. These classifications aren't meant to define words but rather how they are used in a sentence. Learning the different parts of speech gives you the tools to construct well-ordered sentences.
A noun is a person, place or thing. Nouns give us the subjects or direct or indirect objects of a sentence. To avoid repeating the same noun over and over, you can use a pronoun in subsequent sentences. Commonly used pronouns are "he," "she," "you" and "I."
Verbs put action into your sentences, telling us what the subject is doing. Adjectives modify nouns and adverbs modify verbs, adjectives or phrases. In other words, adjectives and adverbs help to better describe words in a sentence. The glue that holds a sentence together is called a preposition, which indicates the spatial, temporal and logical relationship an object has with a subject. Common prepositions are "at," "to," "in" and "with." Conjunctions are chain links between two or more sentences. Common conjunctions are "and," "but" and "or." To express emotion in a sentence, use an interjection. Some interjections are "oh," "ah," "hey" and "ouch." Sentences that use interjections often end with an exclamation point.
There are several ways to improve your spoken English. One of the easiest ways is to engage in conversation. Practice makes perfect, and the more you speak English, the more comfortable you'll be at it. Listen to conversations around you, learning how other people use words and phrases to convey their ideas. Notice if what they are saying is clear and understandable. If you're not comfortable speaking around others, talk to yourself in the mirror.
Read everything you can get your hands on. Words on a page show you how syntax (sentence structure) and diction (word choice) can create better sentences. Reading also helps to improve your vocabulary. When reading or listening, pick up on phrases. You can eventually use these in your conversations. If you don't know the meaning of words you read or hear, look them up in an English dictionary. Make note of them and try to use them in your daily conversation.
