Introduction

Whenever a comparison or list is involved, items must be listed in parallel structure, meaning similar items are compared to each other. Think superficially when comparing for parallel structure. Parallel items typically consist of simple nouns, verbs, adjectives, and adverbs.

Example

The designer specified that the circuit board should have a length of ten centimeters, a width of eight centimeters and a thickness of two millimeters. Incorrect

The designer specified that the circuit board should be ten centimeters in length, eight centimeters in width and two millimeters in thickness. Correct

To struggle for freedom is not as rewarding as achieving it. Incorrect

Struggling for freedom is not as rewarding as achieving it. Correct

Like vs. As

“Like” should be used to only compare nouns. “As” should be used to compare clauses.

Example

My Uncle looks like Batman

My neighbor yelled as though he were a maniac.

Comparative vs. Superlative

When two or more items are compared, make sure you are using the correct comparative word.

Example

My score was higher than Mike’s score

Of Mike, Dan, and Peter, my score was the highest.

Between vs. Among

Between is used for a comparison between two things. Among is used to compare multiple objects.

Example

I can’t decide between chocolate and vanilla ice cream.

I can’t decide among vanilla, chocolate, or strawberry ice cream.

Equal vs. Equivalent

The difference between these two words lies in their degree of impact. Equal means exactly identical. Equivalent means two things are very similar, but not exactly identical.

Example

4+1 is equal to 5.

The United States spent 4 billion dollars on chocolate in 2009, equivalent to the GDP of Somalia.

Semicolon vs. Colon

These two punctuation marks look similar but they are not! A semicolon is used to join two phrases that could stand alone as sentences, instead of using a conjunction (and, but, or, nor, for, yet, so). The colon is used after an independent clause to introduce a list of items.

Example

The Writing Center is open seven days a week; students may make an appointment or walk in any time.

The following energy sources are renewable: wind, hydropower, biomass, solar, and nuclear.
