a curiosity discovered while researching Franz's query

Franz, Zero in Sanskrit is Shunya.

It also stands for empty, void etc.

There is also the adjective rikta = emptied empty void etc. from the
verb ric

Itsn't rikta the source of rectum in Latin rather than "straight" in
which case both "king" and "the end of the large intestine" would be
derived from the same source (that all our bosses have their head
buried up their ass is, I am sure, a modern conceit)?
