Editing Iota subscript (section)

==Terminology==

In [[Greek language|Greek]], the subscript is called {{wikt-lang|grc|ὑπογεγραμμένη}} ({{grc-transl|ὑπογεγραμμένη}}), the [[perfect (grammar)|perfect]] [[passive voice|passive]] [[participle]] form of the verb {{wikt-lang|grc|ὑπογράφω}} ({{grc-transl|ὑπογράφω}}), "to write below". Analogously, the adscript is called {{lang|grc|προσγεγραμμένη}} ({{grc-transl|προσγεγραμμένη}}), from the verb {{wikt-lang|grc|προσγράφω}} ({{grc-transl|προσγράφω}}), "to write next (to something), to add in writing".<ref>{{cite book|first=Eleanor|last=Dickey|author-link=Eleanor Dickey|year=2007|title=Ancient Greek scholarship|place=Oxford|publisher=Oxford University Press|page=256}}</ref><ref>{{cite encyclopedia|encyclopedia=Lexiko tis Neas Ellinikis Glossas|last=Babiniotis|first=Georgios|script-title=el:προσγράφω}}</ref>

The Greek names are [[grammatical gender|grammatically feminine]] participle forms because in medieval Greek the name of the letter [[iota]], to which they implicitly refer, was sometimes construed as a feminine noun (unlike in classical and in modern Greek, where it is neuter).<ref>{{cite encyclopedia|encyclopedia=Lexiko tis Neas Ellinikis Glossas|last=Babiniotis|first=Georgios|script-title=el:υπογράφω}}</ref> The Greek terms, transliterated according to their modern pronunciation as ''ypogegrammeni'' and ''prosgegrammeni'' respectively, were also chosen for use in character names in the computer encoding standard [[Unicode]].

As a phonological phenomenon, the original diphthongs denoted by {{angle bracket|{{lang|grc|ᾳ, ῃ, ῳ}}}} are traditionally called "long diphthongs".<ref>{{cite book|first=Donald J|last=Mastronarde|year=1993|title=Introduction to Attic Greek|url=https://archive.org/details/introductiontoat00mast|url-access=registration|place=Berkeley|publisher=University of California Press|page=9f}}</ref><ref>{{cite book|title=Greek grammar for colleges|first=Herbert W.|last=Smyth|year=1920|place=New York|publisher=American Book Company|page=9}};</ref> They existed in the Greek language up into the classical period. From the classical period onwards, they changed to simple vowels (monophthongs), but sometimes continued to be written as diphthongs. In the medieval period, these spellings were replaced by spellings with an iota subscript, to mark former diphthongs which were no longer pronounced. In some English works these are referred to as "improper diphthongs".<ref>{{cite book|last1=Mounce|first1=William D.|title=Basics of Biblical Greek|date=November 28, 2009|publisher=Zondervan|isbn=978-0310287681|page=10|edition=3rd}}</ref><ref>{{cite book|first1=George Frederick|last1=von Ostermann|first2=Augustus E.|last2=Giegengack|title=Manual of foreign languages for the use of printers and translators|publisher=United States.
