JPSm. p. 324 gives this form with the meaning "traveling, sojourning"; however, that is the correct meaning of ܡܬܟܣܢܢܘܬܐ with two nuns, as correctly given in the Supplement p. 18b. Unfortunately, the page reference to the sole example is incorrect. Bar Hebraeus does use the current form however for that meaning, as shown by Teule, Herman G.B., ed. Gregory Barhebraeus. Ethicon (Mēmrā I). CSCO 534-535, Syr. 218-219. (Leuven: Peeters, 1993) p. 115:3 (according to Simtho; we have not seen the publication).
