*mīna ˀīdaˁ - what I know? (Kogan 2015:338; AHw. 655, Tropper 2000:146, cf. Bulakh 2013b:7‒9)

Formally or semantically similar lexemes are attested more or less throughout WS – Hbr. maddūaˁ ‘why?’ (HALOT 548), OffArm. mdˁm ‘something’ (DNWSI 598), Gez. ˀəndāˁi ‘perhaps’ (CDG 28), Soq. έdaˁ, ɛdáˁ ‘perhaps’ (LS 53) – it is only Ugr. mndˁ that matches Akk. minde exactly in both form and meaning (Kogan 2015:338).
