Morphology

sacrotuberous = tuberous (transparent) = sacro + tuber + ous

Formed by attaching the combining form 'sacro-' (relating to the sacrum) to 'tuberous'; the meaning directly denotes a relation to the sacrum and a tuberous structure.

Etymology

Sacrotuberous comes from sacro- from sacrum, the lower back bone whose name once meant 'sacred', and tuberous from tuber meaning 'bump', as in tuberosity which is a bony lump. So, sacrotuberous means 'relating to the sacrum and the bony lump', which fits the ligament that links the sacrum to the ischial tuberosity in the pelvis.
