ugenki = sun (noun) (some things Google found for "ugenki": a rare term; user names; similar name Genki was a Japanese era in the 16th century and is a Japanese company in the computer and video games industry)
Word derivation for "sun" :
Basque = eguzki, Finnish = aurinko
Miresua = ugenki
My previous Miresua conlang word for "sun" was "urzeni". I changed this word to be more similar to the Basque and the Finnish words, such as having a k as the second to last letter in the word.
