I was thinking about the root word “sume” as in assume, consume, presume, resume, subsume and even, perhaps, exhume.  Here is what it means:

sump, sume & sum
These ROOT-WORDS are SUME, SUMP & SUM meaning TAKE, USE & WASTE. They come from the Latin sumere & sumptus. It is interesting to notice how the idea of taking and using began to mean expensive, burdensome, and wasteful. The layman’s name for tuberculosis is conSUMPtion, a disease that causes the patient to WASTE away. In ancient Greece and Rome there was a SUMPtuary law which forbade lavish spending.
