Similar to the transitional phrase, parallel construction, a.k.a., parallelism, ensures an easy flow for your readers. Anything you can do to make reading an enjoyable experience for them will help keep them coming back for more. So, pay attention to the balance.

Peek in at “Transitional Words and Phrases” and the section on Subject-Verb Agreement” as well.

Grammar Explanations is . . .

. . . an evolving list of the structural rules and principles that determines where words are placed in phrases or sentences as well as how the language is spoken. Sometimes I run across an example that helps explain better or another “also known as”. Heck, there’s always a better way to explain it, so if it makes quicker and/or better sense, I would appreciate suggestions and comments from anyone on an area of grammar with which you struggle or on which you can contribute more understanding.
