PArm
*tənan - smoke (Kogan 2015:397)
The OArm. spelling with t (rather than š) makes unlikely the relationship between PArm. *tənan and Hbr. ˁāšān, Arb. ˁaṯan- ‘smoke’ (HALOT 896, Lane 1954) assumed in LSyr. 828 and Beyer 1984:419 and corroborates its connection with Gez. tann ‘smoke’ and its cognates in modern EthS (CDG 577).
PArm
*ṭly - young man
A semantic evolution of *ṭalay- ‘lamb’, whose original meaning almost completely disappeared from Aramaic
PArm
*ṯawr-(at)- - cow, bull (SED II No. 241, Kogan 2015:400)

No feminine formation from PS *ṯawr- ‘bull, ox’ is attested outside PArm. *ṯawr-at-. The only exception is Arb. ṯawrat-, but this rare word is certainly no basic designation of “cow” in Arabic (in TA 10 338, only one verse by al-Aḫṭal is adduced as an illustration, which may testify to the restricted use of this lexeme).

PArm
*ymˀ/ymy - to swear

Attested from Official Aramaic onwards. The only, semantically very remote WS cognate to the Aramaic verb is Arb. wmˀ ‘to make a sign’. Conversely, the Akkadian verb wamāˀu ‘to swear’ is attested as early as the Sargonic royal inscriptions, so the possibility of an early loan cannot be ruled out (Kogan–Krebernik 2021a:389). 

PArm
*zˁr - to be small (Kogan 2015: 430)
PArm
*zuγayr- - small (Kogan 2015: 430)
diminutive pattern, together with PArm *γulaym- child, otherwise typical for Arb only
PES
*ˀbr - to be old (Kogan 2015: 276)
on meaning shift “sturdy, strong” > “old” cf. Buck 1949:959
PES
*ˀal(a)-b- - there is not (Bulakh 2012)
in the “North Ethiopian” negative particle *ˀal is restricted to the combination *ˀal(a)-b- ‘there is not’
PES
*ˀamlāk- - god (LLA 151, Appleyard 1977:56, Kogan 2015: 455)
Must be analyzed as a broken plural from an unattested *malk- ‘king.’
PES
*ˀanḳoḳəḥo - egg (Dolgopolsky 1973:282, 319, Kogan 2015: 449)
Borrowed from Cushitic according to Dolgopolsky, but treated as cognate to the corresponding Cushitic forms in Militarev 2004:309, 2010:65 (cf. SED I No. 160, Appleyard 1977:27).
