The word that lets you agree without the effort of new words.

means A word used to mean 'the same as what was just said,' sparing you the trouble of repeating it.

from From Italian ditto, meaning 'said' — literally the past participle of dire, 'to say,' tracing back to Latin dictus. It started out in business and legal writing, where the same month or item kept recurring in a list, so instead of rewriting it, clerks just wrote 'ditto' — 'the aforesaid' — and let repetition take a shortcut.
