day 49: still more about the main subject—compound subjects and more

          A sentence’s main subject is usually one of the following:

  a. A noun (person, place, thing, or idea)

            b. A pronoun (a word that replaces a noun—he, she, it, they,
etc.)

A sentence can have one subject, two subjects, or even three or more
subjects.

            a. One subject: Kayla is my first daughter.

b. Two subjects: Kayla and Cami are my first two daughters.

                         c. Three subjects: Kayla, Cami, and Kara are my daughters.

          
A sentence can have one subject at the beginning, and then later in the
sentence have another subject. However, most of your sentences will have
only one subject until you are at a more advanced level of writing.

Tomorrow—putting together the subject lessons and preposition lessons---a sentence’s main subject (and actually most other subjects in the sentence) are not usually found in prepositional phrases!
