-ia Look up -ia at Dictionary.com
word-forming element in names of countries, diseases, flowers, from Latin and Greek -ia, which forms abstract nouns of feminine gender. In paraphernalia, Mammalia, etc. it represents the Latin and Greek plural suffix of nouns in -ium or -ion.

Chinese forms country names by adding guo "country" to the stressed syllable of the place name, hence Meiguo "America," from mei, the stressed syllable of America (minus -r-, which does not exist in Chinese). Similarly Yingguo "England," Faguo "France." Continent names are similarly formed, with zhou "continent" (such as Meizhou "America (continent)," Feizhou "Africa," Ouzhou "Europe").
