    Hi Nguyen,

    I’m not sure why you wouldn’t be able to see it. Maybe clean the cache and try again.

    Hope this helps.

    Hi Engr,

    I’ll see what I can do. In the meantime, find the search box on this site and look for these lessons there. We actually have a few.

    Hope this helps.


That’s a great test


Hello Mr. Adam. Thank you for this class I learnd a lot.I didn’t know all those types of water. :D


So short lesson and so many new information and new words. Thank you, Mr.Adam, it was really useful!


Hi Adam! I guess that in English you surely use the opposite of the phrase ‘fish out of water’, for example, in some situation somebody could feel like ‘fish in the water’, in spanish we do.


    Hi Jorge,

    We have some other expressions, like a pig in mud (very happy) or in one’s element :)


Adam, your lessons are always great, but I would appreciate it if you could sometimes deliver contents focussing on literature as well.

    I’ll see what I can do Kedar ;)


Hi Adam unfortunately in Moscow we can’t drink tap water like you in Canada. It is unpotable. By the way thanks for new vocabulary, especially for brine, potable and desalination words. I’m very interesting in desalination plants. Can you give me some examples of it?


    Hi DinDim,

    That’s a pretty big topic. You can do a Google search on it. They’re becoming more and more sophisticated and spreading in countries with water shortages. Actually, pretty interesting tech.


Thanks for the good vocabulary lesson about water. I learned not only new words but also useful knowledge. :)

    Hi Ismael,

    To be honest, the EngVid tech guys take care of that stuff. I just supply the questions and answers :)


Thank you Adam! It is intereresting ,but we use the phrase – fish in the water-that is mean to feel yourself comfortable.

Thank you teacher, but I don’t understand earth 71% and human 60%?

Farah khalify

    Hi Farah,

    71% of the Earth’s surface is water, while the human body is 60% water. Is this what you meant?


Thank you so much, Adam. Such a useful lesson. I need to talk to someone of engVid team to ask about sort of permission if it’s possible. How can I reach you guys?

Ahmed alnour

Thanks Adam
The lesson was useful to me.


i like you adam you are agreat man


Thank you everyone :)


    Hi MR.ADAM
    unpotable or impotable
    and why?????


Thanks Adam. It’s good enough to know about various type of water.


Thanks so much once again for your videos, Adam!
@1:45, please, when you say “naturally made well”, do we write it with a hyphen (naturally-made…).
I ask that because “naturally” is an adverb and this got me confused!

Further, please, Adam,
@10:13 you say “ANY PERSON who is not in THEIR normal or comfortable place”.
I was exactly looking for it in grammar yesterday but could not find it!
It’s common to see “their” regarding to he or she (previously used in a sentence).
Any class on the subject on EngVid or anywhere else?! Have never studied it before, although very common to see.

Thanks indeed for your kind assistance!

Thank you Adam , its an intersted lesson as ever yours . God bless

Msgdy Alhaddad

Thank you Mr. Adam.

thank a lot, Adam


Hi Adam, you can find natural mineral water in many parts of our world, for example in Germany.

Anne BW

Great lesson like usual.


Very good Mr. Adam. When we think about water, we don’t imagine so many topics on the subject. And there are still waters used in the industry, for example, distilled water, demineralized water, reverse osmosis water, etc.
Water comes so easily to our homes that we don’t even realize how important this element is for the life of the world.
Congratulations on the choice of topic and the excellent presentation.
Thank you very much.
