The Origin of Diddo or Ditto

The correct word “ditto” comes from Italian. It is based on the Latin word dictus, meaning “said.” In the 17th century, English writers adopted ditto to avoid repeating the same word or phrase in lists and records.

Originally, ditto was used in accounting and official documents to mean “the same as above.” Over time, it moved into everyday speech as a casual way to say “me too” or “same here.”

So why does “diddo” exist at all? Simple reason: sound. When spoken, ditto is often pronounced quickly, making the t sound soft. This leads some people to spell it phonetically as diddo, but that spelling has no historical or linguistic basis.
