Answer :
Final answer:
The correct question is "How frequently do you do this?" as 'frequently' is the adverb form needed to modify the verb 'do'. Additionally, the correct sentence structure for a question in English requires the use of subject-auxiliary inversion.
Explanation:
The correct grammar would be to use the adverb form, so the right question is "How frequently do you do this?" When asking about the frequency of an action, you should use an adverb to modify the verb 'do'. An adverb describes how an action is performed and answers questions like how often, how much, when, and where. In contrast, 'frequent' is an adjective, which would be used to modify nouns, not verbs. Additionally, when forming questions in English, typically a subject-auxiliary inversion is required. So the correct question would actually be: "How frequently do you do this?" When it comes to grammar pet peeves, it is important to distinguish between 'mistakes' that are due to the evolution of language and those that may lead to confusion or a lack of clarity. While some individuals may find certain usages bothersome, others may consider them a natural part of linguistic change. Combining grammatical correctness with clarity should always be the goal, regardless of whether the context is formal academic writing or casual conversation.
