With apologies for this brief entry, the General Assembly has pronounced 2008 the International Year of Languages (media release). Thanks to Indigenous Languages Speak for the entry Good News about this announcement.
Although intermittently at first, the United Nations General Assembly generally names each year for a topic of focus. Recently, years have received more than one proclamation, with 2008 the International Year of Planet Earth (a triennium), the Potato, and now Languages. See the Wikipedia entry for the UN years.
