Segol

Segol (Hebrew: סֶגּוֹל ) is a Hebrew niqqud vowel sign that is represented by three dots forming an upside down equilateral triangle "ֶ". As such, it resembles an upside down therefore sign (a because sign) underneath a letter. In modern Hebrew, it indicates the phoneme /e/ which is similar to "e" in the English word sound in sell and is transliterated as an e.
