Old-timer's disease Alzheimer's disease While it is a disease of old-timers, it is named for the German neurologist, Dr. Alois Alzheimer.
Antartic Antarctic Just think of an arc of ants (an ant arc) and that should help you keep the [c] in the pronunciation of this word.
Artic Arctic Another hard-to-see [c]—but it is there.
aks ask This mispronunciation has been around for so long (over 1,000 years) that linguist Mark Aronoff thinks we should cherish it as a part of our linguistic heritage. Most of us would give the axe to "aks."

B

barbituate barbiturate Don't forget this word contains three others: bar+bit+u+rate

Calvary cavalry It isn't clear why we say, ''Mind your Ps and Qs'' when we have more difficulty keeping up with our Ls and Rs. Had there been a cavalry in Jesus' time, perhaps Calvary would not have been so tragic.
