Etymology
the word 'colonnade' entered english in the early 18th century, borrowed directly from french. the french term was itself derived from italian 'colonnata', which is built upon the latin word 'columna', meaning 'pillar' or 'column'. the suffix '-ade', of french and ultimately latin ('-ata') origin, is used to form nouns indicating a group or collection. thus, the literal construction is "a collection or series of columns," a meaning that has remained consistent. the architectural feature, prominent since classical antiquity, logically takes its name from its primary, repeating structural element.
