Troche

A small medicated lozenge designed to dissolve. For example, to soothe the throat as a cough drop. Strictly speaking, a troche should be circular since the word derives from the Greek "trokhiskos" meaning "a little wheel." Pronounced trOh-key. Sometimes mistakenly pronounced trOhsh or trOhshay under the misapprehension that it is a French word.
