“No” has already been sufficiently explained in the previous message UC#1048.
Oscillation (back and forth motion) shows negation whether made with the head or the hand or by water. Shaking the head from side to side means negation and no. The essential feature is the waving or wave, which imitates the wave of water of the hieroglyphic no.
The corresponding motion is the one that indicates yes. Nodding (waving) the head up and down indicates yes because it is a wave rising up above the water.
Additionally, a side to side motion is horizontal or aligned with the equinox, thus means even, neither, none, no. An up and down motion is vertical or aligned with the pole or solstice, thus means odd, either, one or the other, high or low. (NG1 23/41)
In an imaginative sense, I reach the word Yes through Ses. Ses is breath. Thus water and breath are no and ses. Breath is the result of heat in water that causes a cloud of mist to rise, like Yeast. (NG1 148/166; 148/166; 256/274)
In a linguistic sense, Yes comes from an earlier Gese. Taking the G as equivalent to the KH (Eg.), we find the scattered Khi, S, and F, which can be traced back to an ideographic khif, all meeting once more in the Y, and the Y we are taught is Greek, the F is Old French, and the G is Anglo-Saxon. (BB 141/153)
Ia is Yes, in Egyptian (Eg.). Ia, the sign of assent and assuring, can be paralleled by Hes, to obey, be obedient, which goes still farther as Kes, to bow, bend down, be abject. Here are three degrees of Ia, Hes, and Kes. Ia with a mere nod of assent, Hes a bow of obedience, and Kes to bend down abjectly and entreat. The English Y like the J is not a primitive, and was preceded by the G or K. As said before, Yes was the earlier Gese. Yes is also Ges or GlS, as an oath. (BB 147/159)
