Morphology

ergosterol = sterol (semi-transparent) = ergo + sterol

The element 'sterol' clearly signals a sterol, but the preceding element is a specialized chemical combining form not transparently meaningful to general learners.

Etymology

Ergosterol breaks into ergo- and -sterol, and the -sterol part is the same as in cholesterol, which is a 'fat-like molecule'. A helpful way to remember it is that ergosterol is like a 'fungal cholesterol' found in fungi and can turn into vitamin D2 in sunlight.
