How French works
In French, days of the week, months and seasons take a small letter, unlike in English:
Elle est arrivée lundi
She arrived on Monday
On est arrivés le 2 mars
We arrived on 2nd March
In French, names of streets take a small letter, unlike in English:
Il habite 14, rue de la Gare
He lives at 14 Station Road
In French, personal titles take a small letter, unlike in English:
La reine Elisabeth
Queen Elizabeth
le président Chirac
President Macron
le docteur Pomier
Doctor Plomier
le père Joyce
Father Joyce
Languages take a small letter in French, unlike in English:
Elle parle couramment le français
She speaks fluent French
On parle allemand dans cette région de la Suisse
They speak German in this part of Switzerland
By contrast, in French nationalities and countries take a capital letter:
Les Français sont très fiers de leur cuisine
The French are very proud of their cuisine
La France est le plus grand pays d'Europe
France is the biggest country in Europe
But for adjectives relating to nationalities, a small letter is always used:
La grammaire française est difficile
French grammar is difficult
