As part of a name (PN, personal name, or other), or major class being referenced, in capital letters (a Sumerogram form), it is typically separated from other capital letter Sumerograms with a period.
The MEŠ cuneiform is a vertical stroke, followed by three or four angled smaller wedge-strokes.
For example, Amarna letter EA 161, Aziru to Pharaoh, shows a series of six preparation items listed sequentially.
Two basic types of meš signs are either expressed as wedges laid horizontally, following the vertical stroke, or wedges expressed at an angle, at any level of angle, upward, but all of consistent size.
In EA 153 the base line "head" is used as the first wedge-(non-angled), following by the angled wedge-2 and wedge-3.)
