Origin & History of “colon”
There are two distinct words colon in English. Colon ‘part of the large intestine’ (16th c.) comes via Latin from Greek kólon, which meant ‘food, meat’ as well as ‘large intestine’. Colon the punctuation mark (16th c.) comes via Latin from Greek kōlon, which originally meant literally ‘limb’. It was applied metaphorically (rather like foot) to a ‘unit of verse’, and hence to a ‘clause’ in general, meanings which survive in English as technical terms. From there it was a short step to the main present-day meaning, ‘punctuation mark’.
