lirju = book (noun) (some things Google found for "lirju": a rare term; user names; similarly named Liru is a sexy blonde female werewolf in anime Magipoka)
Word derivation for "book" :
Basque = liburu, Finnish = kirja
Miresua = lirju
My previous word for book was bikura. An OK word, but I think I was forcing it to look like the English word book. My new word starts and ends like the Basque word, and uses the letter J, which is uncommon, from the Finnish word. By the way, in Miresua (like Finnish) J is pronounced like Y.
