Following from the American Heritage Dictionary:
au·gust (ô-gúst“) adj. 1. Inspiring awe or admiration; majestic. 2. Venerable for reasons of age or high rank.

I recognize that Caledonian is not equal to American but much of the
American heritage is indeed Caledonian, both of which received considerable
input from Latin. Furthermore nothing is more American than Canada
(formerly CND) which comprises a major portion of north America, but
for unknown reasons does not contain America in its name.
(Is it possible that the "A"s inserted between CND are initials for
"America" rather than the customary "eh?" frequently heard above the parallel?)

Sorry, eh? Couldn't resist, Lad.
