File, variable, array, split

As I learn from you guys, I get more and more ambitious.  Academic career is
sooooo boring in comparison to this! :)

Along the same lines of what we've been doing here with reading files into
variables or custom properties and then turning them into arrays, what if I
wanted to have two words associated with each clickedWord: i.e. If it's a
verb, I want to have the clickeWord retunr both its infinitive AND the
translation.

Arrays can have only one element and one key, as far as I get it.  Is the
only way to do this to create two files (verb + infinitive) and
(verb+translation) and then have two sets of arrays (tTranslations, and
tForms)? 

Also, if I chose to do it with custom properties -- I've read somewhere that
only one set of cutom properties can be active at a time...

I'm stuck again.

Thanks a lot for you patience with me.
