Nouns are words that name people, places, animals, and things. The subject of a sentence is who or what the sentence is about. This subject is usually a noun. Most of the time the subject noun is near the beginning of each sentence.
Every sentence has a subject and a verb. Remember the subject is the noun -the who or what the sentence is about. The subject and the verb (action or state of being) must agree. The rule for the agreement is if the subject is singular (one), the verb must be singular. If the subject is plural (more than one), the verb must be plural.
Adjectives are words that modify or describe nouns. Adjectives can describe what kind and how many. They can describe the nouns that are subjects or nouns in the predicate (object nouns)
Articles are also a type of adjective. These words include a, an, and the.
Linking words and phrases connect ideas. Coordinating conjunctions are words such as: and, but, nor, so, and or that connect two words phrases or sentences. When two full sentences are joined together, it is then called a compound sentence.
