Superposition is necessary for interference to exist.
Superposition is not sufficient for interference to exist.
Superposition and interference are both in the cause and
effect chain of events.

No, just responding to Jim Kelley's assertion that interference
is only an end result. Eugene Hecht says the "intricate color
patterns shimmering across an oil slick ... result from ...
the phenomenon of interference." The intricate color patterns
are the *result* of interference.

# Do you have a reference for the rules of that word game?

It's no word game - it's just English as plain as I can make it.
