Clueless Don, if I were writing about the world's last two anything, that fact about them would surely be worth a comment more precise than "almost unique". For example: "The last two white rhinoceroses in the world met yesterday in Kruger National Park. Unfortunately, both of them are male."

The French loan word "route" generates other problems in Canada, where we live with inexorable cultural pressure from our southern neighbours. We still use the French pronunciation, a homonym of the verb "root", as noted by David Carter(UK). Americans pronounce it as a homonym of "rout", which I understand as a verb that means "scour", "extract" or "put to flight" and is most often applied to defeated armies.

A piece of computer equipment called a "router", so called because it directs wireless signals to the correct receiving device, is American in origin (like most computer equipment), and is therefore pronounced like what happens to defeated armies. Unfortunately, this confuses people (like me) who (a) know what the thing does; and, (b) know about power tools, including the machine carpenters use to make fancy edges on boards and molding.

I wish that were my only problem with the United States of America.
