^Irish makes contrasts between velarized ("broad") and palatalized ("slender") consonants. Velarized consonants, denoted in the IPA by a superscript ‹ˠ›, are pronounced with the back of the tongue raised toward the velum, which happens to the /l/ in English pill in some accents, like RP and General American, but not in Hiberno-English. In Irish orthography, broad consonants are surrounded by the letters ‹a›, ‹o›, ‹u›. Note that the superscript character ‹ˠ› is not a capital "Y" but a Greek lowercase gamma, ‹γ›.
^"Slender" (palatalized) consonants, denoted in the IPA by a superscript ‹ʲ›, are pronounced with the body of the tongue raised toward the hard palate, in a manner similar to the articulation of the ‹y› sound in yes. In Irish orthography, slender consonants are surrounded by the letters ‹e›, ‹i›.
^ ابجدFew if any modern dialects of Irish distinguish all four types of "l" sound. Most dialects have merged /l̪ˠ/ and /lˠ/ as /l̪ˠ/, and some have also merged /l̠ʲ/ and /lʲ/ as /lʲ/. Still others have merged /lˠ/ and /lʲ/ as /l/.
^ ابجدFew if any modern dialects of Irish distinguish all four types of "n" sound. Most dialects have merged /n̪ˠ/ and /nˠ/ as [n̪ˠ], and some have also merged /n̠ʲ/ and /nʲ/ as [nʲ]. Still others have merged /nˠ/ and /nʲ/ as [n]. In parts of Munster, /n̠ʲ/ has merged with /ɲ/ in non-initial position.
^Also /vˠ/ as in the word van for some positions in some dialects.
^ ابجدAll Irish diphthongs have falling sonority; they could therefore more precisely be transliterated as iə̯, uə̯, əi̯, əu̯.
