In general, nationalities work just like regular adjectives: they have to match the noun of the sentence in terms of gender and singular/plural. In French, the nationalities are not capitalized.

Here is a list of nationalities:

Belgian and Swiss French use “septante” in place of “soixante-dix”, which makes “septante et un(e)”, etc., and “nonante” in place of “quatre-vingt-dix”, which makes “nonante et un(e)”, etc.

Vocabulary: Time

In French, “il est” is used to express the time; though it would literally translate as “he is”, it is actually, in this case, equivalent to “it is”. Unlike in English, it is always important to use “heures” (“hours”) when referring to the time. In English, it is OK to say, “It’s nine,” but this wouldn’t make sense in French.

Vocabulary: Days

Notes:

• Quel jour est-il ? is equivalent to Quel jour sommes-nous ?.
• Quel jour est-il ? can be answered with Il est....
• Nous sommes... and Il est... are, of course, not used with hier, aujourd’hui, or demain.
