It also has a common usage in the 1350 BC Amarna letters as the Sumerogram for "man".

In the Amarna letters' Rainey's glossary (Rainey 1970) which is the glossary for Akkadian language words, Sumerograms,[4] etc., for Amarna letters EA 359–379, uses for both LÚ and lú are recorded.

For the Amarna letters in Rainey's glossary, "LÚ" as the Sumerogram becomes Akkadian amēlu,[5] for "man".

The alternate, abbreviated version of LÚ (as seen in the chart above), shows an upward angled base horizontal; the 3-wedges (strokes) are attached to it at approximately a right angle (approximating 90 degrees).

Some of the Amarna letters (for example EA 34), show LÚ in compacted use, and with a high angle for the horizontal-base stroke.

Late form of cuneiform LÚ sign
