Tips

register
骶 is a technical anatomy term and is bound — it does not stand alone, appearing in fixed words like 骶骨 (sacrum) and 骶椎 (sacral vertebrae).

Components

radical
骨 gǔ
bone
The 骨 (bone) radical on the left marks 骶 as a bone of the body — the sacrum. Same radical as other skeleton words like 骼 and 髋 hip.
phonetic
氐 dī
base; foundation; an ancient people
Right side 氐 gives the sound, shifting from dī to dǐ. Its 'base / bottom' flavor also fits well, since the sacrum sits at the base of the spine — so it carries a faint meaning echo. The same phonetic drives 底 and 低.
