“I never learned any grammar.” You may lack conscious knowledge of grammar and grammatical terms (and if so, you are not alone—American students today rarely study English grammar). But you probably understand the ideas that grammatical terms such as auxiliary verb and direct object represent, even if the terms themselves are unfamiliar. Brushing up on the terms commonly used to talk about grammar will make it easier for you and your instructor—as well as other readers and reviewers—to share a common language when you discuss the best ways to get your ideas across clearly and with few distractions.
