semi-colon

The word 'semi-colon' is a modern English compound formed by directly combining the Latin prefix 'semi-' with the word 'colon'. The prefix 'semi-' (from Latin 'semis' meaning "half") was used to indicate that this punctuation mark was perceived as intermediate in strength between the comma and the colon. The term 'colon' itself has a long history, originating from the Greek 'kōlon', which meant a limb, clause, or member of a sentence, reflecting its function in dividing grammatical units. The semi-colon was introduced in the 16th century by Italian printer Aldus Manutius as a typographical innovation to clarify sentence structure, with its name logically describing its role as a "half-colon" or a pause of intermediate value.
