maerae : seas
The Illunse word for seas is maerae. The word for sea is maera. Maerae is a rare last name.
Seas in Latin is maris. Seas in Old English is sae (same as sea).
Here is another type of plural. And this time I'm using that leeway with letters, as there aren't two E available in the Latin and Old English plurals.
I've changed this word. My Illunse word for seas is now maera.
