Dà-Fhoghair - Diphthongs

Diphthongs are sequences of two vowels joined together to act as one (long) vowel sequence.  There are approximately 9 diphthongs in Gaelic.  We can divide these into two classes: (A) those which are spelled using two vowels, and (B) those which are spelled using a combination of vowels and consonants.

These diphthongs occur before

like the last diphthong but the first part of the diphthong is like the unrounded form of [u].  Again, you can produce this sound by making an [u] and spreading your lips at the same time (as if you were grinning widely).  NB: Some dialects pronounce this sound like
