Morphology
The compound is literally analyzable as 'yellow' + 'spot', so a B1 learner would understand it denotes a small yellow mark; however the specific medical sense (the macula, a central retinal area rich in cones responsible for detailed vision) is specialized and not predictable from the constituents alone. Because the basic lexical meaning is transparent but the precise anatomical/technical referent requires domain knowledge, the item is best classified as semi-transparent.
Etymology
Yellow spot (plant disease) comes from the simple image of a small yellow spot on an infected leaf that farmers and gardeners noticed. Because the bright yellow mark showed the sickness, the name now means 'a disease that makes yellow spots on leaves'.
