Grammatically Correct: Mixed Constructions Make No Sense

A sentence that is logical has a subject and a predicate. When a subject is introduced into a sentence, it sets up an expectation about the grammatical direction in which the sentence goes, and when that expectation is not met, the sentence does not sound right.  This is a interesting topic, that causes a lot of confusion.   So please check out this article.

Sentence parts that do not fit together grammatically or logically result in a mixed construction. Although readers will see and hear the logical error first, the cause of the error is often mechanical. Writers force parts of speech to take on grammatical functions for which they are not designed. The example below shows both errors.

For athletes who play contact sports have increased risk of arthritis later in their lives.

The first part of the sentence goes off track between the words sports and have. Most readers hear and see the error immediately. The long prepositional phrase For athletes who play contact sports is in a subject position. By rule, a prepositional phrase cannot be a subject of a sentence. It can only function as a modifier.

Writers can start a sentence with a prepositional phrase by way of introduction, but then they need to add a proper subject and verb in an independent clause, as in the example below.

For athletes who play contact sports, arthritis is a risk later in their lives.

The same problem occurs with adverbial clauses in the subject position. And the same solution is available.

When students are late is very distracting to other students.

The adverbial phrase When students are late cannot be the subject of a sentence. Like prepositional phrases, the function of adverbial phrases is to modify.

When students are late, they distract other students.

But another revision is also possible. Change the adverbial phrase into a gerund phrase. The gerund phrase can be the subject of a sentence.

Being late to class is very distracting.

Or revise the sentence based on who or what is the actor/subject of the sentence.

Students who are late to class are very distracting.

A mixed construction also occurs when writers use a coordinating conjunction to separate a dependent clause from an independent clause. Review the FANBOYS acronym (from my article “Grammatically Correct: Fixing Run-on Sentences”) to remember coordinating conjunctions: For, And, Nor, But, Or, Yet, So.

Although celebrities live charmed lives, yet they can have serious drug problems.

Either although or yet needs to be deleted.

Celebrities live charmed lives, yet they can have serious drug problems.

Although celebrities live charmed lives, they can have serious drug problems.

Sometimes artists draw with their non-dominant hand to bring attention to how their drawing tools affect their creative execution. A way for writers to bring heightened attention to their creative expression is to concentrate on their grammar tools. As a rule, writers do not want to impede the flow of words to page, especially in early stages of a draft. As an exercise, however, noticing subject choices and the verbs connected to them helps writers see where weaknesses in sentence construction occur.
