*ŝVˁ(V)r- - barley (Kogan 2011: 203, Kogan 2015: 199)

PS
*ŝaˁr- - straw, grass (Kogan 2015: 40 n. 87, 199)
A derivation from PS *ŝaˁr- ‘hair,’ assumed as certain in Fronzaroli 1969: 12‒13 and elsewhere in Semitological studies, is difficult to prove, although a contamination with this widespread anatomical term cannot be excluded.
