Sentences consist of words used in specific ways.
These specific ways are known as the parts of speech. Learning to identify the parts of speech in sentences helps students to develop an understanding of how words work together in sentences. Knowing this, a student can analyze their writing, identify and eliminate many grammatical errors, and build sentences that express their exact meaning. A common noun is any noun that does not name a particular person, place, thing or idea and is not capitalized in English unless it is the first word of a sentence. Examples are child, country, rainbow, winter, happiness, etc. 2.
