Grammar usage guide and real-world examplesUSAGE SUMMARY
"did I understand" is a correct and usable part of a sentence in written English.
It is typically used to confirm whether a person comprehended or interpreted something correctly. For example: "I explained the instructions to my friend, and then asked her, 'Did I understand correctly that you want me to meet you at 5 pm?'" In this sentence, the speaker is asking for confirmation that their understanding of the friend's request is accurate. The phrase "did I understand" can also be used in other contexts, such as clarifying a lesson or concept in a classroom setting: "After the teacher explained the math problem, she asked the students, 'Did you all understand how to solve it?'" Again, the phrase is being used to check for comprehension and make sure the students correctly understood the lesson.

Common error
Avoid using "did I understood", as "understood" is the past participle and requires an auxiliary verb like 'have'. The correct form is "did I understand", using the base form of the verb after 'did'.
