SKILL 14: PARALLEL STRUCTURE WITH COORDINATE CONJUNCTIONS

SKILL 14:                           PARALLEL STRUCTURE         WITH COORDINATE            CONJUNCTIONS                                                                             The job of the coordinate conjunctions (and, but, or) is to join together equal expressions. In other words, what is on one side of these words must be parallel to what is on the other side. These conjunctions can join nouns, or verbs, or adjectives, or phrases, or clauses; they just must join together the same structures. Here are examples of equal structures correctly joined by coordinate conjunctions:

He discussed the problem with the nurse and the doctor

The professor was knowledgeable but boring

She hikes, jogs, or rides her bicycle whenever she can.

There are meetings in the morning, in the afternoon and in the evening

You can do the work because you want to do it or because you have to do it

In the first example, two nouns are joined by the coordinate conjunction and. In the second example, two adjectives are joined by the coordinate conjunction but. In the third example, three verbs are joined by the coordinate conjunction or. In the fourth example, three phrases are joined by the coordinate conjunction and. In the last example; two clauses are joined by the coordinate conjunction or.

The sentences that follow show the types of errors in parallel structure that are common on the TOEFL test.

The evening dress was beauty* but expensive.

The student reads each chapter, takes a lot of notes, and memories* the material.

In the first example, the coordinate conjunction but joins the noun beauty and the adjective expensive. The adjective beautiful is needed in place of beauty. In the second example, the coordinate conjunction and joins the verb reads, the verb takes, and the plural noun memories.         The verb memorizes is needed in place of memories.
