Sakuma Y. 2009b, II, 616 suggests
[tar(uya)li-]. A movement of the bird “in front” from
SIG₅-az only allows a movement
tar(uya)li- from this quadrant. However, it should be noted that
peran (‘in front’) in the previous sentence must also be restored; thus, the argument is to some extent circular.
For parallel sentences, see e.g. KUB 18.5+ (=CTH 573.113) obv. II 13 and passim.
Elsewhere in the text the ‘favorable’ side is spelled logographically (SIG₅-az).
