  • did + present tense (or ) Past tense of the verb [duplicate]
    "Did you eat breakfast?" So that is how you can understand why the "did" is there It's an auxiliary which is inserted to replace a null auxiliary once subject-aux inversion takes place (do affixing), and at the same time "steals" the past tense from the main verb, because auxiliaries have to carry the tense when they are present!
  • Does using did to form the past tense make a difference?
    A simple sentence like I did work has to be Emphatic, because Active do is a pro-verb and pro-verbs only occur in certain constructions, which this is not; and Do -Support do never occurs in this construction either -- it's a marker of many constructions, but not of this one Auxiliary verbs are part of the syntax, and may or may not mean anything
  • Use of did not and have not - English Language Learners Stack Exchange
    There is a difference in using 'did not' and 'have not' Let me give you a few examples and then try to explain the usage did not : Case 1 I did not have time - no time at all I did not have lunch - it just means the speaker did not have lunch Case 2 I did not see Joe - it means the speaker did not see Joe I did not go to Paris - I guess you get the meaning have not: Case 1 I have not had time
  • grammaticality - Is it did you used to or did you use to? - English . . .
    Etymologically, “? did you used to” is grammatically incorrect: the auxiliary did must be followed by the base form of the verb, use It cannot be followed by a past participle such as used By this reasoning, “did you use to” is the only correct form This is the conservative prescriptivist answer to your question
  • Using Did should it be followed by past or present tense verb?
    In all three sentences, the tensed verb is did Having both verbs tensed would be ungrammatical, and that's true whether we put the second verb in past or present tense:
  • What is the difference between I did and I have done
    "I did" is the "simple past" form We use the Simple Past to express the idea that an action started and finished at a specific time in the past Sometimes, the speaker may not actually mention the specific time, but they do have one specific time in mind
  • Which one is correct: what did he do or what did he does?
    I am confused about how to use "what did he do" and "what did he does" I want to ask one friend what another friend does
  • word choice - could not or did not? - English Language Learners . . .
    Pondering further over the question, the use of "could not" and "did not" might also seem confusing for native learners when it comes to using the conjunction "so" prior to "could not" or "did not " However I am not sure, but I do know the meaning of "so" as to give reason to something happened, happening, or will happen
  • past tense - When to use did in a question? - English Language Learners . . .
    When to use did in a question? Ask Question Asked 11 years, 7 months ago Modified 6 years, 2 months ago
  • What did you learn today? Vs what have you learned today?
    In that context, "What did you learn today" is correct, at least to my Canadian sensibilities When a parent picks up their child from school and asks them about that day's lessons, they're referring to a finished past time, "today", meaning today is now a completed school day
