Just like the verb être (to be), avoir (to have) is an irregular verb.
Its forms are easiest learned individually. So watch out when using it.
j'
ai
tu
as
il/elle/on
a
nous
avons
vous
avez
ils/elles
ont
What's on?
on is a general way to address a group of people and nobody in particular. We could translate it in English as one: "One always has time to drink tea!"
You sound like the queen...
Yes, it sounds silly in English, but it's not so bad in French. We'll get to that later though.
Here's a quick review of both verbs:
AVOIR
ÊTRE
je, j'
ai
suis
tu
as
es
il, elle, on
a
est
nous
avons
sommes
vous
avez
êtes
ils, elles
ont
sont
The verb avoir is also used to form many common expressions:
avoir froid
to be cold to have cold
avoir chaud
to be hot to have hot
avoir soif
to be thirsty to have thirsty
avoir faim
to be hungry to have hungry
Cool, but do I need to know all of these?
Oh no, of course not, but it helps to be aware of this. You'll learn these and more expressions as you go along!
I'll focus on getting avoir and être right first...
