Usage Note

Spelled colonel but pronounced "kernel" (the middle 'l' and first 'o' are silent). This is one of the most irregular spellings in English — learners must memorize it separately from how it sounds. Frequently used as a title before a surname: Colonel Wolfe.

Common Mistakes

The colonel /kəˈlɒnəl/ gave the order.
The colonel /ˈkɜːrnəl/ gave the order.
the first 'l' is silent and the 'o' sounds like 'er', not 'ah'.
She was promoted to coronel.
She was promoted to colonel.
the spelling has an 'l' after the 'o', not an 'r'.

Synonym discussion

Sense: noun/1

Colonel is a specific senior military rank, whereas officer is a broad term covering anyone who holds a position of authority in the armed forces. A commander refers to someone who leads a unit, regardless of their exact rank — a colonel may be a commander, but not all commanders are colonels. General is the rank above colonel, commanding larger forces, while major is a lower rank below lieutenant colonel. Lieutenant colonel sits directly below colonel and is sometimes confused with it. In short: colonel names a precise rank with specific insignia, while officer, commander, and general describe scope of authority or higher-level positions. For example, a lieutenant colonel might lead a battalion, but a colonel typically commands a regiment and several battalions under it.

Etymology

LatinItalianFrenchEnglish

Colonel entered English in the 1500s from French 'coronel', which came from Italian 'colonnello' (the leader of a column of soldiers). The Italian word traces back to Latin 'columna' (column). English kept the Italian spelling 'colonel' but kept the French pronunciation 'kernel', creating one of the most famous spelling-pronunciation mismatches in the language.
