Language in Laos. The official language of Laos is Lao, a tonal language closely related to Thai. Thanks to ubiquitous Thai broadcast media most Lao understand Thai fairly well, but it's worth learning a few basic expressions in Lao.
Laos is also home to hundreds of species of orchids and palms. The forests and fields support a wealth of wildlife, including nearly 200 species of mammals, about the same number of reptiles and amphibians, and some 700 varieties of birds. Common mammals include gaurs (wild oxen), deer, bears, and monkeys.
