History

Perspective
Early evidence of ditto marks can be seen on a cuneiform tablet of the Neo-Assyrian period (934–608 BCE) where two vertical marks are used in a table of synonyms to repeat text.[6]

In China the corresponding historical mark was two horizontal lines 𠄠 (Unicode U+16FE3 𖿣 OLD CHINESE ITERATION MARK), which is also the ancient ideograph of "two", similar to the modern ideograph 二. It is found in bronze script from the Zhou dynasty, as in the example at right (c. 825 BCE). In seal script form this became 〻, and is now written as 々; see iteration mark.

The word ditto comes from the Tuscan language,[7] where it is the past participle of the verb dire (to say), with the meaning of "said", as in the locution "the said story". The first recorded use of ditto with this meaning in English occurs in 1625.[7]
In English, the abbreviation "do.", usually italicised, has sometimes been used instead of ditto marks - see example below, and also in a table in a U.S. Patent.[8]
Other languages
For Chinese, Japanese and Korean, there is the specific Unicode character U+3003 〃 DITTO MARK in the range CJK Symbols and Punctuation. This facilitates the setting of both marks on a single horizontal line in Asian vertical text.
Other languages may use equivalent symbols. For example, in Norwegian and Swedish handwriting, a version using horizontal lines to indicate the span of the cell in a table where an entry repeats is sometimes seen (––〃––).[9] In French, it is called a guillemet itératif, but the actual symbol used may vary: » is used in Quebec, while in France ― is preferred.[10]
