Vowel-initial words are sometimes written with an unpronounced h, especially if they are very short (the preposition i "in" was sometimes written hi) or if they need to be emphasised (the name of Ireland, Ériu, was sometimes written Hériu).
Ord som inleds med vokal skrivs ibland med ett outtalat h, särskilt om de är mycket korta (prepositionen i "i" skrevs ibland hi) eller om de behöver betonas (namnet Irland, Ériu, skrevs ibland Hériu).
