French people are mostly catholic. Here they say: we are catho. They use often abbreviations.
In stead of computer= ordinateur, they say : ordi. When I phoned to make a restaurant reservation, the girl said: I am sorry I was working on my ordi.
A rain-coat is an impermeable, they often call it : my imper.
A disaster is in French a catastrophe, but in the every day language they say a catar.
The next example is also very common, when they use ' as usual'= comme d'habitude, they use to say comme d'habe.
And the last one for today; breakfast=petit déjeuner= petit dèj.
So if you come to France and want to talk like the French, use one of these abbreviations!
