  1. Acetabulum: In Ancient Roman measurement, the acetabulum was a measure of volume equivalent to the Greek ὀξύβαφον. It was one-fourth of the hemina and therefore one-eighth of the sextarius. It contained the weight in water of fifteen Attic drachmae.
  2. Acetabulum in invertebrate zoology is a saucer-shaped organ of attachment in some annelid worms and flatworms. It is a specialised sucker for parasitic adaptation in trematodes by which the worms are able to attach on the host. In annelids, it is basically a locomotory organ for attaching to a substratum. The name also applies to the suction appendage on the arms of cephalopod molluscs such as squid, octopus, cuttlefish, Nautilus, etc.
  3. Acetabulum: In ancient dining, an acetabulum was a vinegar-cup, which, from the fondness of the Greeks and Romans for vinegar, was probably always placed on the table at meals to dip the food in before eating it. The vessel was wide and open above; and the name was also given to all cups resembling it in size and form, to whatever use they might be applied. The cups used by jugglers in their performances were also called by this name. They were commonly of earthenware, but sometimes of glass, silver, bronze, or gold. In anatomy, because of its shape, the acetabulum is the place of pelvis that meets with the head of the femur, forming the hip joint.
