·    No glyphs given in K&H.

·    JM.p195.#4 – day name.

·    SJ.302.3.

·    Variants – there are two subtle variants:

o Longish snout: snout points downwards after leaving the face at an angle.

o Short (almost non-existent) snout: snout points to the left.

·    OK vs. TZ’I’:

o K&L and BMM9 both distinguish OK from TZ’I’ as two distinct logograms.

o Conversely, TOK and S&Z both explicitly indicate that they can be used / read interchangeably.

o For the sources which make this distinction, it looks like TZ’I’ has a snout pointing diagonally downwards (northeast-to-southwest axis) whereas OK has a snout which is horizontal and points directly to the left.

·    Vowel length - long-o vs. short-o - there appears not to be universal consensus on the length of the vowel:

o MHD is quite clear on this: OK = “dog” vs. OOK = “foot”.

o However, TOK (which writes vowels as long when they are deemed to be long) gives (only) OOK = “dog”.

o BMM9 gives both, with OOK before OK (though there may be no particular significance in the order).
