Subject: Does ther term 'osmosis' only apply to water or to all solvents?

I am just trying to figure out what the actual definition of osmosis is.

I have read definitions that say "water" and many that say "solvents" 
or "solvents (usually water)".  The last would seem to specifically include 
solvents other than water.  

Normally I can just look up definitions and it isn't a problem but I can't 
seem to find a consistent definition on this term.  What makes one definition 
more correct than another?  Who is the authority on science definitions?  How 
can I actually KNOW what the definition is?

Hopefully an answer will clear this up for me.  An example or two of whatever 
you deem relevant would probably help too.  I don't want to use the term out 
of context.

Thank you.
