Id (cuneiform) Another sign is similar to "lu", but has only 1-vertical, left and right, ku (cuneiform), and the Amarna letters is usually so compact, that hardly any of the individual strokes can be easily identified. Another sign is similar in this group to cuneiform "ur", but the center is replaced by 2 stokes, one angled down, and the other a wedge (at extreme right vertical), and is the "gáb" sign. In the Amarna letters it is often used for English "all", or "all (of us)", Akkadian language, "gabbu". (Amarna letters EA 153, EA 287, EA 288, and EA 267)--> Id (cuneiform)
Ab (cuneiform) Ab (cuneiform) The cuneiform ab, and ap sign, (in the Akkadian language world, 'b' is unaspirated, formed with the lips, and 'p' is "aspirated"-(aspirated consonant, with the breath)) is the cuneiform sign used for the syllables "ab", or "ap", or the vowel and consonant usages of a, b, or p. In the Akkadian language b-and-p are interchangeable; also in cuneiform texts, any vowel of the "a, e, i, u" (no "o" in Akkadian) can be interchanged with another. Also for the 'ab/ap' sign, there is a capital letter (majuscule) usage as a sumerogram, found in the "Epic of Gilgamesh" for
