*rwḥ - to blow (Kogan 2015: 96; Bulakh 2005b:415‒420)
see also *rV̄ḥ - wind
PWS
*rwm/rym - to be high, tall, long (Kogan 2015:97)
PWS
*rwṯ̣ - to run (Kogan 2015: 122)
This root does not seem to be attested in Arabic: Arb. rwḍ ‘to train a riding beast’ is quite remote both phonetically and semantically The widespread equation with Akk. râṣu ‘to come to help’ is semantically uncertain, even if the meaning shift “to run” > “to help” is sufficiently well attested in Indo-European (Buck 1949:1353‒1354)
PWS
*rwy - to be abundant (water); to drink abundantly (CDG 478; Kogan 2011: 239; Kogan 2015: 97)
PWS
*sḥb - to draw, to drag (Kogan 2015: 97)
PWS
*str - to cover, to hide (Kogan 2015: 97, HALOT 771, CDG 518)
PWS
*šgy - to wander (Arkhipov 2018: 170)
PWS
*šḥr - to be white on black or black on white (Kogan 2005c:191)

May be tentatively compared to Akk. šūru, šuḫru if the latter indeed denotes dark color as suggested in AHw. 1287 (Bulakh 2003: 13–15; Bulakh 2006: 195–196).

*šḥm - dark-brown hue (Bulakh 2004: 277–278; Kogan 2011: 199)
