Money

The unit of money in Lojbangug is the rupnu, which is divided into 100 fepni. The exchange rate is currently about 15 Lojbo rupnu to the American dollar.

Lojbo have the odd habit of referring to everyone else's monetary units as rupnu too. To distinguish them, one can say merko rupnu or meryru'u for the American dollar, fraso rupnu or fasru'u for the French franc, etc. To be absolutely clear, the Lojbanic rupnu can be known as a jboru'u or lojru'u.
