Although
Sakuma Y. 2009b II, 539 read the sign as
GUN, the second component of this sign (GÚ+UN) is missing. Not necessarily this is to be considered a mistake, as a few cases exist where the form can be understood as an abbreviation of the standard term; in particular, four attestations in KUB 52.24 (CTH 573.86) exclude this is a mistake. See the text edition for a discussion and other examples.
