aa (ah-ah) noun
Lava having a rough surface.
[From Hawaiian, apparently from the sound one emits on touching the hot lava surface.] (Italics mine)
Aa is one of the two kinds of lava typically found in Hawaiian volcanoes.
The other kind is pahoehoe, one with a smooth, ropy surface. You can see their pictures at:
“Aa has a surface that’s broken into blocks with sharp, spiny projections.”
Ian Skilling, Lavas and Life, The World & I (Washington, DC), Jul 1998.
“With so much to memorize, trying to recall that aa is a kind of solidified lava or that an ai is a three-toed sloth, would tax the brain unnecessarily. Mr. Keskaroonkul estimates he knows nearly 110,000 words, or nearly 70% of Webster’s New World Dictionary, published by Merriam-Webster. In comparison, the average college graduate is said to have an active vocabulary of 10,000 to 15,000 words.”Joseph Pereira, Hard Scrabble: Thais Who Play Very Well Learn the Dictionary — But Some Have No Idea at All What the Words Mean; Why Clutter Up the Mind?, The Wall Street Journal (New York), Jul 19, 1999.
