In this work, we investigate the ability of LLMs to explain revisions in sentences. We introduce a new dataset demonstrating a novel task, which we call explaining text revisions. We collected human- and LLM-generated explanations of grammatical and fluency edits and defined criteria for the human evaluation of the explanations along three dimensions: Coverage, Informativeness, and Correctness. The results of a side-by-side evaluation show an Overall preference for human explanations, but there are many instances in which annotators show no preference. Annotators prefer human-generated explanations for Informativeness and Correctness, but they show no preference for Coverage. We also examined the extent to which the number of revisions in a sentence influences annotators{'} Overall preference for the explanations. We found that the preference for human explanations increases as the number of revisions in the sentence increases. Additionally, we show that the Overall preference for human explanations depends on the type of error being explained. We discuss explanation styles based on a qualitative analysis of 300 explanations. We release our dataset and annotation guidelines to encourage future research.",
