To know - How to use the verb "savoir"

I think it's time for you to learn a very important verb in French.
Oooo sweet, what is it?
It's the verb savoir, which means "to know".
But... I've used it before, haven't I? I can already say "je ne sais pas".
Haha, correct! Let's have a look at the other forms of the verb.
The verb savoir is an irregular verb. This means that the conjugation is a little different to other verbs.
For instance, savoir has two roots. One with SAI:
Je
sais
Tu
sais
Il/Elle/on
sait
And another one with SAV:
Nous
savons
Vous
savez
Ils/Elles
savent
And here are a few examples of the verb used in a sentence:
Je sais marcher sur les mains.
I know how to walk on my hands.
Tu sais où est le Louvre ?
Do you know where the Louvre is?
Vous savez parler français.
You know how to speak French.
Elles savent comment je m'appelle.
They know my name.
