falyopwíkat [ɸə.lʲoˈpˠi.kət], meaning “river valley”. This is a late loan from Muipidan flophïyk’ïdo, itself a mangled reduplication of flo “green”.
When loaning words from Muipidan, the Kharulians would include the Muipidan noun class suffix and definite article (in this case, -k’ïdo; the stem is flophïy). But then analogy would kick in. Kharulian uses the suffix -o for the accusative case, and this voices the last consonant of the stem: et “food” has accusative edo; lyat “seed” has accusative lyado, etc. So they treated loaned Muipidan noun forms like falyopwíkado as the accusative, and derived the nominative falyopwíkat by analogy.
