Begun is correct.
The correct phrase is "I have begun." "Begun" is the past participle form of "begin."
No. The past tense is began, and begun requires a helper verb (be, have).They began the project together.They had begun the project together.They will have begun their new project by May.The project was begun by them. (passive)
Has began is correct grammar. The rain has began fits more than the rain has begin. In place of "has" you could use "will" or "should." The rain should begin.
It should be "has the show begun?"
The correct spelling would be "ever since the world began".
The correct way to say it is "summer has begun." This is the present perfect tense so it requires an auxiliary verb like "have" and the past perfect conjugation of "begin" which is "begun." "Began" is the past tense of "begin," which is used by itself in a sentence.
Neither is correct."Began" is the simple past tense of "begin". The race began at 7:00."Begun" is the past participle of "begin". Past participles are used to create the past, present, and future perfect tenses (along with the auxiliary verbs has, have, had, and will).Past perfect: I/we/you/he/she/it/they had begunPresent perfect: I/we/you/they have begun; he/she/it has begunFuture perfect: I/we/you/he/she/it/they will have begun"Is" can be used with the present participle (beginning) to create the third person singular, present progressive tense: he/she/it is beginning.
In grammatical terms, it's this: "began" is past tense and "begun" is the past participle.What this means in use is that if you are talking about something in the simple past tense, you would always use "began." These sentences are correct:- I began music lessons when I was 6.- The story began in the Colonial Period.- Where were you when the game began?- Our relationship began when we were in high school.A participle can't be used all by itself as a verb. Another verb has to go with it. So you can't say something "begun." You have to say it "has begun," "had begun," "was begun," "will be begun," and so on."Begun" would be wrong in every one of the examples above and in any other sentence like them.Here are some correct uses of "begun." Notice the helping verb (the auxiliary verb) that goes along with it. The verbs can be separated--such as by "not"--but they still work together.- You cannot be seated after the play has begun.- I have begun a shopping list.- We have not yet begun to fight.Likewise, if you are using "had" or "have" or another auxiliary, you must use "begun" and not "began." These sentences are all wrong:WRONG - Have you began your assignment?WRONG - My shift had began at 3:00.WRONG - The party has not began yet.
Begun is the correct spelling.
"You have begun" is correct.
If you mean grammatically, no, the proper speech would be "the lectures have not (or haven't) begun yet".
