Hypodiastole

'lower separation [mark]'), also known as a diastole,[1] was an interpunct developed in late Ancient and Byzantine Greek texts before the separation of words by spaces was common.

[2] The hypodiastole was similar in appearance to the comma and was eventually entirely conflated with it.

In Modern Greek, ypodiastolī́ (υποδιαστολή) refers to the comma in its role as a decimal point, and words such as ό,τι are written with standard commas.

A separate Unicode point, ISO/IEC 10646 standard (U+2E12) (⸒), exists for the hypodiastole but is intended only to reproduce its historical occurrence in Greek texts.
