hip: English has two hips. The anatomical hip [OE] comes from a prehistoric Germanic *khupiz, whose formal and semantic similarity to Greek kúbos ‘six-sided figure’, hence ‘pelvic cavity’ (source of English cube) suggests that the two may be related. The rose-hip [OE] goes back to a West Germanic *kheup-, which survives also in Dutch joop ‘rose-hip’. => cube
