Final answer:
A mixed-construction sentence is a sentence that contains parts that do not fit together due to grammatical structure or meaning. This occurs when a writer begins a statement in one way or direction, and then unintentionally changes grammatical paths. These sentence errors can detract from an otherwise solidly analytical text.
Step-by-step explanation:
A mixed-construction sentence is a sentence that contains parts that do not fit together due to grammatical structure or meaning. This occurs when a writer begins a statement in one way or direction, and then unintentionally changes grammatical paths. These sentence errors can detract from an otherwise solidly analytical text. For example, if someone writes, 'I was going to the store and buys apples daily,' it is a mixed-construction sentence because the verb 'buys' does not agree with the subject 'I'.
