Declension
Note: etymologically, the declension should follow the pattern for Latinate nouns ending in -ia (see e.g., ), and thus contain geminated i in the genitive, dative, locative and genitive plural. However, the word is highly assimilated, and thus the native feminine declension with single i is also common. Current usage on the Internet seems to favor the geminated i form by around 3:1.
