All languages I know of have four basic directions: left, right, backwards and forwards. Are there any that don’t?
Maybe you could have just three: forwards, backwards-left and backwards-rigth? Or more then four, maybe with distinct names for some or all of the four in-between the common ones
Also the Sun moves in one direction across the sky, along with everything else on the Ecliptic. So that defines one axis, with the perpendicular being another.
