Q:

Original source of the term "Siaynoq"?

Re-reading the Dune novels, and I remembered an old question:
What is the source of the term "Siaynoq" as found in God Emperor of Dune?
Most of the non-english terms in the Dune universe come from languages like old Hebrew, Farsi, Arabic, Latin, etc.  But i can't seem to nail down this one term.
I'm not looking for the in-universe definition.

A:

sihanouk means Jaws of the Lion in Sanskrit......
