Very interesting… lesson :-D
8 replies correct out of 9
Thanks, Adam ;-)

Monday, February 16th 2015

    Really interesting. Read my profile….

    Tuesday, February 17th 2015

      Challenging topic for a lesson! Isn’t there any rules to use these prefixes propperly?

      Do we have to develop a “feeling” abou the language in order to use them correctly?

      Oh Gosh! That provides plenty of food for thought Adam.

      Engaging lesson Adam, but at the same time a bit complicated.

      Regards

Fantastic lesson!
I’m looking forward to watching your advanced suffixes lesson. Sorry, What do you mean by saying “novel books”? Is like (Harry Potter, Lord of the rings) books?
Cheers
Thiago

Monday, February 16th 2015

    Hi Thiago,

    Yes, those are good books. They don’t have to be fantasy, though those are good too ;)

    Thursday, March 5th 2015

That was pretty good Adam. I’ve always had a hardtime understanding all those “boring buds”. lol

Thanks for that great lesson.

Monday, February 16th 2015

i found this very difficult but i get 9/9

Monday, February 16th 2015

Oh dear my score is awful it is useful lesson but It is hard for me. Thanks Adam

Monday, February 16th 2015

Prefixes are interesting. Thank you, Adam :)

Monday, February 16th 2015

Adam you are awesome.Good lesson as always.
Congratulations!

Tuesday, February 17th 2015

10 out of 10! Thanks Adam!

Tuesday, February 17th 2015

    do not lie! There were only nine questions.

    Tuesday, February 17th 2015

      “Do not lie”

      Laughing out loud here …

      Sunday, March 1st 2015

    you liar

    Monday, May 4th 2015

Thank yoy very much Adam, this is a very good lesson.
You know, I many times think about the fact that in my language(italian), there is many “rules” that really are not rules, that I use correctly but, I don’t undestand why.
Yes, I’m agree with you, it’s just about feeling and reading, in this case, is very important for improve itself, as much as films are important for pronunciation.
So, i like this lesson, and I got 100 in the test, so, I’m happy for this.
Thank you man :)

Tuesday, February 17th 2015

Tons of thanks dear Adam. I especially enjoy your pronunciation, and teaching style. I wish you good health and productive activities regarding English teaching.

Tuesday, February 17th 2015

Very good lesson Adam!, more words to add to my list, thanks so much!

Tuesday, February 17th 2015

Thanks for the lessons,, it was really great. Anyway i would be really grateful if you could make a lesson about “Apparently” “Subsequently” “Reportedly” “Presumably” Many thanks Adam :)

Tuesday, February 17th 2015

    Hi Saab87,

    That’s probably a little too focused for a lesson. so:

    apparently = seems like, looks like. We say this when we don’t want to make a factual statement.
    subsequently = after this
    reportedly = someone else said this
    presumably = it’s a guess prediction, without fact

    Hope this helps.

    Thursday, March 5th 2015

      Thank you ever so much Adam. You’re very helpful. Your method of teaching is greatly appreciated by me, thanks again, cheers mate :)

      Thursday, March 5th 2015

it not so easy!

Tuesday, February 17th 2015

6/9 Hard one. Again, I did it and always with you. Normally, I understand when I ought to use this prefixes, or the meaning of them in a sentence, but the responses to the quiz I gave a shoot on my own foot. 6/9 argh….it hurt very

Tuesday, February 17th 2015

great lesson , keep up Adam, you are helping alot

Tuesday, February 17th 2015

Adam is my favourite male teacher here

Tuesday, February 17th 2015

    mine too

    Saturday, February 21st 2015

Adam u are the best I understand ur English very well.

Tuesday, February 17th 2015

What about stress changing patterns? Sometimes stress shifts depending on whether the word you form using these preffixes is a noun or an adjective – though it might be quite erratic. You should’ve mentioned a thing or two about this; otherwise, an excellent lesson.

Tuesday, February 17th 2015

    Good point Soarq. I’ll keep it in mind net time :)

    Thursday, March 5th 2015

9 out of 9 ! Thank you Adam. As always you are very clear and brilliant !

Tuesday, February 17th 2015

Thank you Adam…. You did very clearly, and we do appreciate that. I don’t find any question to ask because you’re so great…god bless you.

    I agree with you Josy! That’s a terrific score for a tough lesson.

    Haven’t you studied prefixes before Josy? How come? Well, there’s always a first time.

    Good luck with your English.

    Saturday, March 14th 2015

Thanks for the interesting lesson. You are a good teacher.

Tuesday, February 17th 2015

Tuesday, February 17th 2015

Hi teacher,as usually,your lessons are very useful,furthermore your pronunciation is so clearly.Thank you

Tuesday, February 17th 2015

Thank you so much Adam

Tuesday, February 17th 2015

Thank very much Adam for your videos, all of them are very helpful and I’m always looking forward to watching a new video made by you because your explanations are very straightforward and fun as well. I wanted to ask you to do a lesson on prepositions such us “under, beneath, underneath, below, over, above, on top of, upon” because sometimes they are a little bit confusing. Maybe for you as english native speakers isn’t hard to use them in a sentence, you don’t think about what preposition use, but for me and some other people it’s a little difficult since in many cases the word has just one meaning in our language like the case of “under, beneath, underneath, below”, all of them mean “debajo de” or “abajo” in spanish for example (my mother language). Either way whether you reply to this request or not, I just want you know that I’m really grateful to all teachers from “EngVid” because of your help with English learning.

Tuesday, February 17th 2015

    Thank you Dick95. I’ll see what I can do about these. It’s a good point you make. :)

Wednesday, February 18th 2015

It was a great lesson.

Friday, February 27th 2015

Really interesting

Friday, February 27th 2015

Thanks, Adam.
Could you make a video about plural verbs?
Especially those uncountable nouns can add ‘s’ behind.
E.g. shortage and shortages or wind and winds
What is the difference? In what situation should I use ‘shortages’ and ‘winds’?
It’s so confusing.
Hope you can help. Thanks.

Saturday, February 28th 2015

    I’ll get on it Sophie :)

    Thursday, March 5th 2015

Sorry.
Type it wrong.
It should be uncountable nouns not plural verbs.

Saturday, February 28th 2015

GREAT!
INTERESTING!

Saturday, February 28th 2015

I gues.I have the worst grade from all who finished the quiz.i got just 33 points.But the lesson was very interesting,i should watch it once again.

      Wednesday, March 18th 2015

Hi again Adam! How one must correctly to ask about birthday? It would be great if you also wrote 10 questions(something about dates or something else)that I could use in everyday life. Thank you very much.

Sunday, March 1st 2015

    Hi Katrin,

    I think ‘when’ pretty much covers anything:

    When is your birthday?
    When were you born?

    If you want more vague questions, you can ask what’s your sign? (zodiac sign)

    Is this what you had in mind?

    Thursday, March 5th 2015

      Thank you very much Adam for the answer.

      Friday, March 6th 2015

thank you Adam I really liked your lesson
I think it is very useful.

Tuesday, March 3rd 2015

Thursday, March 5th 2015

    Hi 0101Hades,

    I’ll try to make a video, but for now:

    will–when the future action is decided at the time of speaking.

    going to– when the action was decided before and plans have been made.

    Does this help a little?

    Tuesday, March 24th 2015

Friday, March 6th 2015

    Hi Delkhoshi,

    I would begin by building a vocab base (especially focused on your area of expertise), then start with basic grammar, like parts of speech, clauses, verb tenses, and articles. Then get into the detailed areas that are giving you trouble.

    Hope this helps a little.

    Tuesday, March 24th 2015

lessons are great! make me understand english better!

Sunday, March 15th 2015

adam, well some of those lesson you have taught are quite easy but still all in all i find hard to understand…no offensive maybe i should feel the root first before i use any prefixes, am i right?

Thursday, March 19th 2015

    Hi Blackraid,

    Of course. If you don’t know the word, the prefixes won’t help much. The lesson was more about knowing the differences between the prefixes and how to apply them to the roots. :)

    Tuesday, March 24th 2015

adam, well some of those lesson in prefixes you have taught are quite easy but still all in all i find hard to understand…no offense maybe i should feel the root first before i use any prefixes, am i right?

Saturday, March 21st 2015

    I’ll get on it :)

    Tuesday, March 24th 2015

9 replies out of 9! But it’s very challenging topic. I just feel like that but can’t explain to the students because I’m not a Native speaker. So, thanks a lot, I’m really grateful, it helps. Could you hold a lesson about identifying and non-identifying relative clauses. I know the rule(where to put commas), but sometimes in practice it doesn’t help because the challenge is to feel which information is essential and which is additional. I mean the handbook says: “Look, here is the bike that my father made with his own hands.”(could we use “which” instead?) – We don’t use commas. “I quite enjoyed the tea and the cakes,which Alice made for us.” Was I right to explain that in the first sentence we don’t use commas as we can spot this bike repared by dad’s hands from a variety of others,so it is identifying information? I’m still hesitating…

Monday, March 23rd 2015

teacher I would like to help, I can understand the English however I can not speak or form sentences, you can give me some tips I am very interested in learning more. Sorry i had to use google translator

Tuesday, March 24th 2015

thankyou teacher for lesson

Thursday, March 26th 2015

Hello, Adam! I wanted to say that your lessons are really clear and useful. Could you please explain one thing I’ve noticed watching movies. People say “of note” as notable and “of interest” as interesting.Is there any difference and Is it the obsolete way of speaking,for Ive seen this only in historical movies so far. And can i use it in academical essay?

Tuesday, March 31st 2015

Thank you Adam for this lesson! I strongly agree with you, because like another languages we have to “feel” which prefix would be more appropriate.

Thursday, April 2nd 2015
