Le bled is a colloquial word with two meanings. The first one is the country an immigrant (or a descendant of immigrants) comes from. It is mostly used when talking about North Africa, because it comes from the Arabic word for “country”.
Je suis allé au bled cet été.
I went to my home country during the summer.
The other meaning is a little pejorative and means “town” or “village”, especially a boring and isolated village.
Mes grands-parents habitent dans un bled paumé, il y a même pas de magasin.
My grandparents live in a backwater village, they don’t even have a shop there.
