Saying CW and CCW is really no different than saying right and left. The same perspective issue exists for both.

 @Dorythefish When the thumb moves towards the right, the pinky moves towards the left and vice versa - one has to know which part of the circle is being described by "left"/"right" - it's usually the top. Thinking about rotation relative to a point *outside* the axis is not intuitive for everyone, hence the preference of some for CW/CCW, or the need for a mnemonic that specifies which part is left/right. @eishiya  Right or left from what frame of reference? Since that nmeumonic doesnt establish an FoR, you cant tell. But CCW and CW have implicit frames of reference since they're literally defined by how analog clocks work. |
@leadore CW/CCW has one perspective issue (looking from the cap end, or the tip end/hole), whereas left/right has *two*: that one, plus whether you're looking at the lateral movement at the top or the bottom of the circle of motion.
I often get confused about the latter, but never the former, since I am almost always manipulating the screw from cap end, even if I'm looking at it from another angle.
