Äia (Äi)
Father-in-law. Although it, äio or äiolane (äi:äio in Võru dialect) also means ‘devil’, with all its adjectival consequences: damn, bloody, fuck(ing)... shedding a grim light on in-law affinities. By the same logic, äiatar, the female demon or Devil’s daughter, would thus mean wife... Curiously, while ema and emä are mother in Estonian and Finnish, mom, mommy, etc., in Finnish is äiti. See Hõimu. Another street fractionally outside Tallinn, in Iru.
