It's in the notes https://duome.eu/tips/en/gd :
Vowels in Gaelic hate each other. Specifically, they hate to be seen next to one another. When two vowels appear together in Gaelic, one is often dropped. This makes Gaelic streamlined, like a wet cormorant.
The vocative particle a is dropped before a vowel because of this vowel vendetta. Masculine names beginning with vowels still slenderise.

Ealasaid (Elizabeth - a woman's name)
