>What was once shaved ice is now shave ice, and I now see "ice tea" on menus, instead of the erstwhile "iced tea". Is there a trend to drop the "d" from adjectives, and what do you think of this?

You may well laugh at my educate guess, but I think it's a much-publicize trend largely attributable to misinform people whose overrate teachers should have made more concert efforts to ensure that their underprivilege students received a well-round education.
