I never thought about this common mistake. It helped me with pronunciation. Thank you!

Tuesday, October 18th 2011

    Thank you, after I learn about could have should have and would have. I feel so glad

    Tuesday, October 18th 2011

thank you its so important for us because iam kurdish & not know about english thank you so much

Tuesday, October 18th 2011

    some basic mistake you made in that sentence, and I know English is not your first language because of that you find it hard. I know everyone means you it’s eg it is, its normally means belonging to someone; I or we do, should be at the start of the sentence, and you do not need an ampersand (&). Plus you are using know in the wrong context (way). Here are some para phasing/redoing of your sentence
    thank you it’s this is important for us/me because I/we am Kurdish and do not know much English, i thank you.
    If you using, us use we and if using I use me; in the sentence you gone to, a loads of people to just yourself.

    Thursday, May 16th 2013

      am/are Kurdish. And unsure if a common or about after much and before English

      Friday, May 17th 2013

In the quiz, you should have written bare infinitive, not just infinitive. Because infinitive is the verb that starts with to.

Tuesday, October 18th 2011

    This has been fixed. Thanks for your feedback, Shorty.

Thank for this lesson.

Wednesday, October 19th 2011

thank you Jon.

I would like to ask you about the question 1 in the quiz .. it was: “I could ______ eaten that steak.” I solved it without have and it gave me wrong =( why? .. I followed your sentence which you wrote it in the video “I could eat chocolate” and you didn’t use have here =O, maybe I did’nt understand it well, could you please explain to me more, I would be grateful =)


Wednesday, October 19th 2011

    Hi friend
    Jon forgot to explain something….
    the two sentence “I could eat chocolate” and “I could have eaten(after have always past participle) chocolate” have a slight different meaning. Both sentence are refer to the past but the second, than the first, it shows us the feeling not to do the action to eat chocolate, I could eat chocolate but I couldn’t. It’s a regret. I hope not to make you further confusion. Bye

    Friday, October 21st 2011

      Hi =D

      WOW thank you very much for your explain. Now it’s clear to me, I’m just confused with “have” when we used it and when we don’t need to use it =)

      really thanks -Best Regards-

      Saturday, October 29th 2011

I feel an important point is missing here – why do you use the contracted form “‘ve” instead of “have”? It depends on the stress and the implied meaning, check these examples:
1) I COULD have eaten that … (It was possible for me to do that in the past and I still have the possibility of doing that in the present – “have” can’t be contracted).
2) I could HAVE eaten that … (It was possible for me to do that in the past but I don’t have the possibility of doing that in the present – “have” can’t be contracted).
3) I could’ve EATEN that … (Here “have” can be contracted).
The meaning implied in the third example is something similar to “instead of”, but it’s commonly used with the meaning of 1) above, and that’s what adds (in my opinion) to the confusion.

Wednesday, October 19th 2011

this is helpful to some people and to me. to add, what have nocited to these model verbs they always end either with the past perfect tense or simple past tense…..thank you guys keet it up to you good work.

Thursday, October 20th 2011

thanks a lot a bout the lesson but whats the basic roles for making a sentences?

Thursday, October 20th 2011

    I suppose the most basic rule is that a sentence should have a subject and a verb. But I like to think less of rules and more in relation to what you are trying to communicate.

    Saturday, October 22nd 2011

it was great!

i have a question that what’s the difference between infinitive and bare infinitive?

Thursday, December 29th 2011

thanx alot mr: jon

Friday, January 6th 2012

Thank you Jon. I believe this is a common mistake for a native speaker.
If this helps Engstud:
Infinitive: “to work”, “to have”, etc.
Base form (or bare infinitive): “work”, “have”
Thanks Jon

Friday, January 6th 2012

I would be very thankful to Engvid team.this is very useful website to me.Thanks again!!!!!

Sunday, January 15th 2012

Hi Jon!
I’ve got a problem with your first sentence. You said: “I would have picked you up, but I ran out of gasoline.”
In Hungary I learned Conditional this way:
“I would have picked you up, but I HAD run out of gas.”
Your second example is in the same form as mine, but I really don’t know why you used simple past intstead of past perfect.
Can you help me, please? Thanks, and best regards from Hungary!

Tuesday, January 17th 2012

All right Jon! It is all clear!
I didn’t notice the conjunction. It is BUT, not if.

Tuesday, January 17th 2012

This lesson is not good because you are just write some sentence and right about grammar. But you explain it is not clear and does not have more example. And explain how to use could have , should have or would have. However I would have thank to your lesson

Tuesday, January 17th 2012

thanks for this great lesson. now i understood. but could you plz explain what is the difference between rather or either in your next lesson.

Thursday, January 19th 2012

i really enjoy your lessons. I think you are great teacher.this topics are really helpfull for me .

Wednesday, February 29th 2012

very poor explanation

Saturday, March 10th 2012

This was a good lesson. I’ve already seen this mistake on e-mails. Anyway, I wonder if you can please explain more the pronunciation of these modals as a native speaker (when it’s contracted)including might have + PP. Ronnie has a video similiar like this one but she didn’t include the pronunciation of might. I would like to know how it sounds when spoken.


Saturday, March 10th 2012

Monday, April 30th 2012

Dear Jon,
thank you very much for your lesson. I have a question out of your subject: the place of comma. As in another lesson, if you put a comma between to sentences that is incorect. I mean there is not a comma before “but” anf “if” in your two first examples. Is that right? Thank you!

Friday, May 4th 2012

could u teach me about that??

Tuesday, December 25th 2012

god bless to engvid

Tuesday, January 29th 2013

Thanks for this great video. I do have a question. At the beginning of it, you said something like “I got” would’ve, could’ve… Or maybe you said “I’ve got” would’ve … so my question is which one did you say? I mean, I just can not tell the difference when people say “I got” or ” I’ve got”. Nor do I know when to use which.

Similarly, I can not tell the contraction “I’d” is for would or had.

Thanks for reading my questions. Looking forward to your reply or maybe a great video on this.

Monday, February 11th 2013

Thank you John. I really appreciate your lessons. You are a good teacher, thank you:)

Saturday, February 23rd 2013


Saturday, February 23rd 2013

Mr. Jon.. when i should use “should, would and could” in the sentence…?

thank u.. :)

Saturday, March 2nd 2013

Can I ask you question? In this sentence (found in the dictionary) why has “WOULD BE BOXED IN” been used instead of “WOULD HAVE BEEN BOXED IN”? The whole sentence is in the past tense and the fact that her son could have been boxed in didn’t happen! Look: “She didn’t want to send her son to a school where he woud be boxed in by so many rules and regulations”…I really don’t get it, and many times I’ve found this sort of sentence…

Sunday, March 3rd 2013

how about this.Harry’s daughter must have spent much of her time in hospital due to the illness. Harry and Sally would not have had a vacation in two year.

Thursday, March 14th 2013

Thank you for this lesson. It was great.
