Middle Irish retained the Old Irish consonant inventory,[5] though some assimilation and simplification of consonant clusters occurred. Stops were dropped when adjacent to /l/ or /n/, e.g. Old Irish cland ("progeny") > Middle Irish clann /klaN/. /ṽ/ lost its nasalisation before a vowel, e.g. Old Irish memaid (s/he broke) /meṽaðʲ/ > Middle Irish mebaid /mevaðʲ/, while /v/ was nasalised after nV, e.g. Old Irish noeb ("saint") /noiv/ > Middle Irish náem /noiṽ/. Initial /m/ was additionally fortified to /b/ before liquids /r/ and /l/, e.g. Old Irish mrath ̈(treachery) /mraθ/ > Middle Irish brath /braθ/.[6]
During the Middle Irish Period, the nuclei of multisyllabic vowels shifted from those of Old Irish to the initial secondary articulations of the succeeding syllable, e.g. Old Irish duine ("person") /ˈdu.nʲe/ > */ˈduʲ.nʲe/ > Middle Irish /ˈdʷi.nʲe/. In interconsonantal /e/, this also involved a post-vocalic /ᵃ/ ephentesis, which briefly resulted in /CeᵃC/ before shifting to /CʲaC/, e.g. Old Irish fer ("man") /fʲer/ > */fʲeᵃr/ > Middle Irish fear /fʲar/.[6] Disyllabic proclitics also lost their initial vowels, e.g. Old Irish inna ("of the" [fem.]) > Middle Irish na,[7]. Unstressed vowels were reduced to /ə/,[7] while the Old Irish diphthongs /ai/, /oi/, and /ui/ first shifted to */əi/, and were then monophongised to /əː/.[8] In Ireland, a process of simplifying two vowels in hiatus to a single long vowel occurred except for the late /ia(ː)/ and /ua(ː)/. In Scottish Gaelic, hiatus were retained to the present.[6] These processes created the following inventory of vowels and diphthongs:
At the end of the Middle Irish period around 1200, scribes began using digraphs bh, gh, mh to indicate the fricatives /v/, /ɣ/, and /ṽ/ (lenited versions of /b/, /g/, and /m) by analogy with the lenited ch, th, ph. Lenition of these respective stops went unmarked.[9] Diacritics derived fround the Ancient Greekrough breathing mark (◌̔) could also be used to represent lenition.[note 1] However, both methods remained sporadic and irregular until at least the 16th century, in the Early Modern Irish period.[10]
In addition to the previously described diphthongs, digraphs could also stand for a vowel followed by an off-glide, which then shifted to a non-palatalised back vowel or a palatalised front vowel:[6]
↑In this article, the early modern ponc séimhithe, or overdot, is used to represent diacritical lenition representations.
