EI EI
Let's take a look at how to pronounce the vowels ei in Gaelic.
Ei is another sound that has both a long and short form, represented by a grave accent over the e for a long sound. The short ei sound (without a grave accent) can be heard in deich (ten) and leisg (lazy):
ten
lazy
a lazy girl
Alternatively, èi with a grave can be heard in cèilidh (a gathering) and èigh (shout):
a gathering
shout
