Morphology
free + central + placentation
The phrase is largely compositional: 'placentation' refers to ovule placement, 'central' indicates a middle location, and 'free' signals lack of fusion, so a learner can roughly infer ovules on a central column without internal walls. However, the exact botanical sense of 'free' (not fused to ovary walls) and the technical nature of 'placentation' mean a B1 learner who knows the words but lacks domain knowledge may not derive the precise meaning; therefore it is only partially transparent.
Etymology
Free central placentation literally names the inside of a flower: free means not attached to the inner walls, central means in the middle, and placentation is the place where the ovules (young seeds) sit, so the ovules grow on a single column in the middle of the ovary. That's why the term describes ovules attached to a free central column rather than to the walls.
