Eo.
The sound of eo is either made up of the sounds of both vowels, or like that of o alone.
1. Made up of (2) e and (1) o: e very short, o long, as, beo alive, eolas knowledge; o short, as, beothail lively.
After a Lingual or a Palatal, not quiescent, the e loses its sound, and only qualifies that of the preceding consonant; hence,
2. Like (1) o: long, as, leomhann a lion; short, as, deoch drink.
