To be up to…

Текстовая расшифровка видео и перевод на русский язык:

Hey everyone! Today I want to briefly touch a few things.
“To be up to something” has two meanings.

Let’s start with the meaning number 1: “to be up to a job”
In the example “ Sara is up to a job” means she is able to take responsibilities
and challenges connected with this.

Meaning number 2. A better example would be, you are trying to get some
sleep and you hear there is a lot of music, a lot of noise coming from your
neighbours. So, you knock on their door. Your neighbour opens the door and
you are like: “Guys what are you up to? You know, it’s like twelve a.m.
in the morning I’m trying to get some sleep.” So, this guy is wondering what
they are doing.

You can also ask: “What are you up to this weekend?” So basically you want to know «what
you are doing».

Another thing would be really useful: “What’s up?” You frequently hear this phrase.
What does it mean? And first of all, its origin is a well-known cartoon character
Bugs Bunny. He used to say…he actually usually says: “What’s up, doc?” And what does
it mean? Briefly, “hello”, “how are you?” or “how are you doing?” So, it’s an alternative
way of saying “hello” informal. Really frequently used by the young generation.
And the most common answer to this would be: “Nothing much”

I hope this is going to be helpful for you.
