PES
*dammanā - cloud (Kogan 2015: 448)
Thought to be borrowed from Cushitic by A. Dolgopolsky (1973:51) and D. Appleyard (1977:36). A. Militarev (2004:299‒300, 2010:58) prefers to treat the EthS and Cushitic terms as cognates.
PES
*dmš - to wipe out, to efface (EDA II)
PES
*dndn - to be fat, stout (CDG 136)

Further compared to Akk. danānu, and Ug. dn, the latter is being highly uncertain.

PES
*fgm - to knock down (EDA I 167)
PES
*fkḥ - to become bright, to be ripe, to be happy (EDA 267)

Probably compare with Akk. nepelkû, napalkû ‘to be wide’. 

PES
*fḳḳ - to stand aside (?) (CDG 164, Kogan 2015:385, note 1080)
Cf. PArm. *npḳ ‘to go out’.
PES
*flḳ - to spill out (CDG 160)

According to Leslau, related to *plḳ with a metaphoric semantic shift.

PES
*fls - to emigrate (CDG 160)

May be related through a semantic shift “to emigrate” < “to detach, to separate”.

PES
*fss - to spill, to pour (EDA I 406)

A comparison with Akk. pašāšu ‘to anoint’ is possible.

PES
*ftr - to hit, to kill (EDA I 513)
