Pronunciation

Colonel , with its medial l pronounced as , illustrates one source for the apparent vagaries of English spelling: divergence between a word's orthographic development and its established pronunciation. In this case, English borrowed from French two variant forms of the same word, one pronounced with medial and final , and a second reflecting dissimilation of the first to . After a period of competition, the dissimilated form triumphed in pronunciation, while the spelling colonel became the orthographic standard.

Etymology

Origin of colonel

1540–50; < Middle French < Italian colon(n)ello, equivalent to colonn(a) column + -ello < Latin -ellus diminutive suffix; so named because such an officer originally headed the first column or company of a regiment

Explanation

A colonel is a commissioned military officer in the U.S. Army, Air Force, or Marines who ranks above a lieutenant colonel and below a brigadier general. We still say colonel like the French word it comes from, coronel, which means "chief." To your ear, it probably sounds like "kernel." A colonel leads a regiment, but there are many other levels of officers, all generals, above him. Just below the colonel is the lieutenant colonel, which means colonel’s aide, and below that is the rank of major.
