Sabaic

ˀys₁, ˀs₁ - man, male, warrior (SD 10)

The plene spelling of the word is enigmatic (according to Stein 2003, 56, not in Old Sabaic).

PCS
*ˀinš- - man, person (Kogan 2015: 177, 382)
Loss of -n- in Hbr., Arm. and Sab. (presumably, *ˀinš->*ˀĩš->ˀīš) remains problematic in spite of the obvious presence of -n- in the Hebrew plural form ˀănāšīm (constr. ˀanšē).
