haelon : sky
The Illunse word for sky is haelon. Haelon is a rare first name and a rare last name. In Old English similar word hǽlan means to heal, cure, save. Similar Haelen is the name of a place in the Netherlands.
This word is a mixture of the Old English word for sky which is heofon (sky, firmament; heaven) and the Latin word for sky which is caelum (the sky, heaven, heavens).
My previous Illunse word for sky was haelom. I decided to end the word in N instead of M.
Here's a link to Sky, in J.R.R. Tolkien's words.
