### For what it's worth: a problem in our quest for meaning, is that all 
terms from "normal" English unfortunately :-) come burdened with meaning. 
Any experienced methodologist must have come across this problem, and at 
the risk of stating the trivial to many of you, the most productive 
solution in my opinion always was to invent a new term and to load one's 
own meaning onto it (by defining formal properties, usage, constraints, 
...). Isn't that what we as ontologists, foremost and almost by definition, 
are supposed to do?

### For ORM/NIAM (remember, LOTs and NOLOTs a while back?) we coined the 
term "pater familias", often abbreviated to "PAF" for that little extra 
distance to spurious interpretation --some people think in Latin it 
seems--, for the Object/Thing/Entity/ 
Referent/Supreme_supertype/Whatever... It is of course the same as what 
e.g. John Sowa denotes with a "T"-like symbol in his book, but PAF is less 
ascii-challenged. As a matter of fact, a simple "T" would *also* do fine as 
long as nobody thinks it stands for universal
truth or so  :-)
