This (singular) -> These (Plural)
That (singular) -> Those (Plural)

@Nike: é and è (in addition to ê) depend on the context.
é can be used in verbs depending on the tense used, or an adjective.
French is complicated, it's not too easy to explain.
In example:
> Je suis très fatigué.
So "Je" is obviously the subject, "suis" is the verb, "très" is an adverb and "fatigué" which in this case is an adjective. "Très" here will imply that you're very tired (kinda makes sense already, doesn't it?). For the most part you kinda understand the whole thing but yeah these two letters are very different and they do differ in the pronunciation too.


Fun fact:
Gateau (which is pronounced gató) in French means cake,
Gatto in Italian means cat.
So basically a french cake means cat in Italian.
This is so not true it's just for the lulz
