Just as in economics textbooks the word "
widget" refers to a product whose nature is irrelevant to the present point and therefore unspecified, so in writing about a medical career, a physician whose specialty need not be identified has been facetiously called an
"omphalologist".
Omphalos is
Greek for "navel", and
omphalology would be the medical specialty that treats thereof, if such a thing existed.
The original spelling of the Greek word is:
- <math>{\rm OM}\Phi{\rm A}\Lambda{\rm O}\Sigma.\quad</math>
