Are the accusative and nominative plural cases the same for Knight and Guest? Also, how many cases are there in Valyrian?
- nom pl. azantyssy
- acc pl. azantī
- nom pl. zentyssy
- acc pl. zentī
This is in the nominative case because the verb to be / sagon preserves the nominative case. (This happens in some natural languages too, for example, German.) sagon is seen here as issi (the third person present tense plural / they are ).
