To correct the sentence "A vegan a term that is a contraction of the word vegetarian is a vegetarian who consumes no animal or dairy products," the punctuation error that needs to be addressed is the lack of a comma after the word "vegetarian."
Explanation:
1. A vegan, a term that is a contraction of the word vegetarian, is a vegetarian who consumes no animal or dairy products.
- By adding a comma after "vegetarian," the sentence becomes grammatically correct. The comma is necessary to set off the non-essential clause "a term that is a contraction of the word vegetarian."
This correction helps the sentence flow better and clarifies the relationship between the different parts of the sentence. The comma after "vegetarian" indicates that the clause "a term that is a contraction of the word vegetarian" provides additional information about the term "vegan."
