Gardiner lists only the common forms of Egyptian hieroglyphs, but he includes extensive subcategories, and also both vertical and horizontal forms for many hieroglyphs. He includes size-variation forms to aid with the reading of hieroglyphs in running blocks of text. In contrast, for example, the Budge Reference has about 1,000 hieroglyphs listed in 50 pages, but with no size variations.
Gardiner does not cross-index signs; once a sign is put on one of his lists, other significant uses may be overlooked. One example of this is 𓅒 G16, nbtỉ, the ideogram for the Two Ladies, goddesses Wadjet as the cobra and Nekhbet as the white vulture. These are the protective and patron goddesses of the separate Egyptian kingdoms that joined into ancient Egypt, who were both then displayed on the uraeus of Wadjet when the unification occurred and afterward considered jointly to be the protectors of Egypt and the pharaohs. This ideogram is listed only in the bird list (G), and overlooked on the deity list (C) and the reptile list (I).
Other subcategories included by Gardiner are abbreviations and personalized forms, and also a complete subset, used on papyrus, specifically for the Book of the Dead.
56 signs in Gardiner (1957:242–247), with A59 "man threatening with stick" inserted after A25 "man striking with left hand hanging behind back", and two variants A14* "blood interpreted as ax" of A14 "man with blood streaming from his head"; and A17* "child sitting with arms hanging down" of A17 "child sitting with hand to mouth".
42 signs in Gardiner (1957:485–492).
N3 is an Old Kingdom variant of N2.
N11 "moon" has vertical (increscent and decrescent) variants, N12 is a 19th-Dynasty variant of N11.
Usually depicted with three rays, older variants may also have four rays.[1] Determinative for e.g. pḥḏ "to shine, illumine" and wbn "rise"; from this latter case, it can also take the phonetic value of wbn when standing on its own, e.g. in wbn "wound". Alternatively, it is either a determiner or ideogram for ḥnmmt, the name of the "sun folk" of Heliopolis (Gardiner p. 486).
A depiction with four rays is found on an ivory wand of c. 2100 BC: The "Sun with rays" hieroglyph is shown once, placed upon the head of a ram. It has a central dot, like the "Sun" hieroglyph (N5), with four elongated, undulating vertical rays.[2] See also Aten.
