Mugyodong Bugeoguk House's Dried Pollock Soup

20210423, #breakfastdiary 69, 18°C/partly cloudy Today's breakfast is store-bought: dried pollock soup from #MugyodongBugeoguk House. According to the National Institute of Korean Language, '북엇국' (bugeotguk) is formed by combining '북어' (dried pollock) and '국' (soup), and since the second syllable is pronounced tensed (like [kkuk]), the sai-siot rule (Hangeul Orthography Rule 30) says it's correctly spelled with that extra linking 's,' as in '북엇국.'
