G1. "Ænima?" What's that all about?
The Tool tradition of mystery continues with the title for their latest album. The title is reported to be a mix of the words "Anima" (a Jungian term) and "Enema" (you know). It also perhaps pays homage to a book recommended in the band's newsletter called "Ægypt."
G2. How do you pronounce "Ænima?"
As they do with good music, DJs across the country are butchering the pronunciation of this not-quite-a-word. Some of the band have been heard saying "enema"; though I'm told it is pronounced "ON-ima", giving a nod to the two words which comprise this title. This despite the fact that most words beginning "Æn--" should be pronounced "Een--", but they made up the word, so they can have their cake and eat it too, I suppose.
G3. Suppose I want to type that A-E thingy?
To represent that dipthong in HTML, you need to type an "&" sign, followed by "AElig;". So, to type the album title, enter:
& AElig;nima ...without that space after the &.
Mac users, type option-', or option-shift-'.
PC users, type ALT-1-4-5 or ALT-1-4-6, or ALT-0-1-9-8.
