User:Mahagaja/Irish dh and gh

The digraph dh (also written ḋ, especially in Gaelic type) represents the lenition of d, both synchronically (word-initial position only) and historically (mostly word-internally and finally). Word-initially, dh is pronounced when broad and  when slender, as in dhorn  "fist" (lenited) and dhearg  "red" (lenited). Noninitially, broad dh is not pronounced directly at all in most circumstances, but it can have an effect on how neighboring vowels are pronounced.
