Morphology
crystal + clear
The meaning 'extremely obvious or perfectly clear' is directly derived from combining 'crystal' (a highly transparent substance) with 'clear' (visible/unobstructed or understandable), so the phrase's image straightforwardly intensifies clarity. This compositional adjectival intensification is cross-linguistically common, making it predictable for a B1 learner who knows both constituents.
Etymology
Crystal clear comes from the image of a bright, perfect crystal, like a glass you can see through, where light passes and you can see everything under it. That's why it means 'completely transparent' and easy to see through.
