Morphology

once + bitten, + twice + shy

The literal parts ('once' = one time, 'bitten' = hurt by a bite, 'twice' = two times, 'shy' = cautious/timid) give a clear metaphorical scaffold: being harmed once leads to greater caution next time. However, the proverb’s elliptical form and conventionalized meaning require mapping the metaphor to the pragmatic sense 'becoming wary after a bad experience', which is not completely predictable for an uninstructed B1 learner. Because constituents point toward the intended idea but the phrase is conventional and somewhat figurative, it is best classified as semi-transparent.

Etymology

The saying once bitten, twice shy comes from a clear image: if you are bitten once, you become shy, meaning 'careful', the next time. That's why the phrase means 'careful because of a bad experience'.
