opermedon : afternoon
The Illunse word for afternoon is opermedon.
This word is a mixture of the Old English word for afternoon which is ofernón and the Latin word for afternoon postmeridianus (of the afternoon).
As seen in an earlier post, the Illunse word for noon is medon. But oper will not be the word for after. Like the Old English word ofer, the Illunse word oper will mean beyond or over.
Back in Anglo-Saxon times ofernón meant after 3PM, instead of after 12PM. I assume that the Latin word postmeridianus meant after solar noon. Illunse may follow Latin here.
