Morphology

x-axis = x + axis (transparent) = x + axis

The word is a straightforward combination of the letter 'x' (the variable/coordinate label) and 'axis', so its meaning is directly deducible.

Etymology

X-axis comes from the letter x, which in algebra often stands for an 'unknown' number, and axis, a word like 'axle' meaning a central line. So the x-axis is the main horizontal line on a graph where you put the value you control, like time.
