(A short sentence joined by and is sometimes combined without a comma.)  A semicolon can take the place of the conjunctionA conjunction is a word that joins other words, phrases (groups of words), or clauses (groups of words with a subjects and verb).  Source: Lesson 201 and comma.  Only clauses closely related in thought should be joined to make a compound sentence.

The conjunction should express the proper relationship between the clauses. And joins ideas of equal importance. Or joins clauses that express alternatives. Nor joins negative ideas together. But joins clauses that express contrasting ideas.


Instructions: Combine the following sentences using the appropriate co-ordinate conjunctionsCo-ordinate conjunctions join words, phrases, or clauses of equal rank. They are the following: and, but, or, nor, for, and yet. (For and yet can only join clauses.)
