Is jāhon 2nd or 3rd person?
I know this is a late reply but, "jāhon" is a Possessive Third Person Singular Pronoun.
Shouldn't jahon be translated as "its" ? Where zyhon would be his/hers ?
In High Valyrian the grammatical genders are not directly connected to animacy. See valoqar (younger brother or younger parallel cousin) whose gender is aquatic and its possesive pronoun is jāhon.
