E caudata

Part of a Latin book published in Rome in 1632. E caudata is used in the words Sacrę, propagandę, prædictę, and grammaticę. Note that the spelling grammaticæ, with æ, is also used.

The e caudata ("tailed e", from Latin: cauda "tail") is a modified form of the letter E that can be graphically represented as E with ogonek (ę) but has a distinct history of usage. It was used in Latin from as early as the ninth century to represent the vowel also written ae or æ or in old Gaelic texts from the 13th century to represent an ea ligature.^[1]

In Middle and Early Modern Irish manuscripts, and in unnormalised transcriptions of them, e caudata is used for e, ae and ea.

In Old Norse manuscripts, e caudata was used for both short and long versions of /æ/. In a few texts on Old Norse, it, like German ä, represents short /æ/, the result of i-mutation of Proto-Germanic */a/, and contrasts with e, which represents Proto-Germanic */e/. However, because these two vowels eventually merged to /e/ in the written varieties of Old Norse, they are commonly both written as e.
