What is a Mixed Sentence Construction?
A mixed-construction sentence contains parts that do not fit together because of grammatical structure or meaning. These sentence errors occur when writers begin a statement in one way or one direction and then unintentionally change grammatical paths. This kind of sentence construction can detract from an otherwise solidly analytical text.
Example 1
Mixed Sentence 1: Learning to ballroom dance it has shown increased agility, and you live longer.
- First Problem: The reader expects a verb to follow “learning to ballroom dance” (the subject) so that learning will mean something. But the word it interrupts before the verb appears. It is a pronoun, which takes the place of a noun, so this is basically a second subject.
- Second Problem: The second part of the sentence, “and you live longer,” is confusing because it introduces you instead of continuing the main idea (or subject) of learning to ballroom dance.
To eliminate confusion, you would have to rewrite either the first or the second part of the sentence.
Revised: Studies have shown that learning to ballroom dance increases agility and lengthens life span.
In fact, because it is the dancing itself and not the learning that has these effects, the sentence could be edited further.
Further Revision: Ballroom dancing has been shown to increase agility and lengthen life.
In the following examples, the writer needs to revise either the second part to fit with the first part or the first part to fit with the second.
Example 2
Mixed Sentence: By starting my general studies classes last semester gave me the opportunity to take classes in my major this fall.
Second Part Revised: By starting my general studies classes last spring, I had the opportunity to take classes in my major this fall.
First Part Revised: Starting my general studies classes last spring gave me the opportunity to take classes in my major this fall.
Read the following mixed-construction sentences, and note the ways they have been corrected.
Example 3
Mixed Sentence : For people who have hobbies, they are happier than others.
Revision: People who have hobbies are happier than others.
Example 4
Mixed Sentence : The required qualification is someone who writes well.
Problem: The qualification (the subject) is the ability to write well, but the stated object is “someone”; a person is not a qualification.
Revision: The required qualification is the ability to write well.
Further Revision: The company requires someone who writes well.
Example 5
Mixed Sentence: Nurses, an excellent career choice, involves an extra semester.
Problem: Nurses are not a profession, nursing is.
Revision: Nursing, an excellent career choice, involves an extra semester.
Just Because… Doesn’t Mean and Is When Constructions
Just because . . . doesn’t mean constructions are common in speech but should be avoided in writing. They are another example of mixed sentence construction.
Example 6: Just Because . . . Construction
Just because I want to work in Washington doesn’t mean I’ll get a good job there.
- Revision: Simply wanting to work in Washington doesn’t guarantee a good job there.
- Revision: Although I want to work in Washington, I will need to find a good job there.
Another common mixed construction in spoken English involves the use of when. This construction should also be avoided in writing.
Example 7: Is when. . . Construction
A feeling of accomplishment is when I finish revising a paper.
- Problem: “A feeling of accomplishment” is a noun phrase followed by a linking verb. This construction means that what follows the verb either describes the noun or renames it in different words. When, however, is an adverb referring to time, and in this sentence, it begins an adverb clause. In other words, “a feeling” cannot be the same as or described in terms of time.
- Revision: A feeling of accomplishment is finishing revising a paper.
- Revision: I feel a sense of accomplishment when I finish revising a paper.
