English Vocabulary: Words with the prefix UNDER-
A prefix is a short word that is attached at the front of another word to form a new word. The prefixunder means less, lower, not enough, beneath, or below. So when you attach it to some words, it will change their meanings. For example, underground means beneath the ground. Underdeveloped means not developed enough. In this lesson, we will build our vocabulary base with words that start with the prefix under. We will look at words like undertake, understudy, undergo, underachieve, understate, and more. Do not underestimate the importance of learning new vocabulary! Vocabulary underlies good communication skills in any language. Don’t forget to do the quiz after watching to test your understanding.

Thank you, teacher.
Hi, Adam. Have a good day.
I like to watch your lecture & most of your lessons are easily to understand.
But let me advice when you explain some grammar or vocabulary, please add sample usage more than now if possible.
Thanks a lot Sir.
Thank you so much Adam. Interesting new vocabulary to use from now on!!
This wasn’t rather easy to me, so I learnt a lot. Thank you Adam for this lesson.
So, to be sure, I understand that ‘under’ is not all the time ‘under’ as we thought. Take care not be underwhelmed !
Good advice Marienba :)
Thank Adam..it’s really useful to me
I never thought it would be that easy to understand the lesson, may be I’m good at learning or Adam is good at teaching and for the record I am right behind those who say that Adam is a good teacher.:-) Many many Thanks Adam your the best.
It’s a good explanation and quiz like a resource to solidifies that words. I think is not easy put them in a context. But! It’s not impossible , thank you and all the best.
Hi Adam, thank you for the lesson, this is a useful vocabulary.
Hello!Mr Adam, it was really a helpful course from you, and I still have a compound word though, undercover, does it mean to go above the cover and show yourself as an example?I hope you would answer my question Mr Adam
Hi Mohamed,
Undercover means in disguise, or hiding your true identity. Police do this sometimes to catch criminals.
Does this help?
A good thecher ! thank you sir
Thanks
Plz explian the meaning of underachieve
Hi Saraenglishssc,
Underachieve means not be as good at something or not do something as well as you can.
Very smart kids who should be able to get As in school underachieve because they don’t put in a strong effort and end up with Bs and Cs.
Does this help?

Hello,

Hi Adam,
I saw your video lesson at website, it’s amazing. I follow your instruction to here（Engvid）, but I can’t find any video lessons. Could you please help?
Hi, Soma Yan. Our videos are on YouTube, so they can’t be viewed in China. You can watch many of our videos on Bilibili!
Hello, Adam. I got 9/10. Why “undergo” isn’t correct answer of 1st question, only “undertake”?
Hi Sofysm,
Undergo means a process that someone else does to you, like an operation or an investigation. Undertake is something that you begin to do, like a project or a task.
Does this help?
Yes. Thank you, Adam :)
