Single words aren't too useful, because there are many ambiguities. You'd better use simple sentences.
Another thing: Be very careful about capitalization.
I just got "Sie means they". Yes. In a way.
But the "sie" that you mean is written with a lower-case "s" (unless at the beginning of a sentence, of course).
So my immediate reaction was: this must be the form of address "Sie".
Of course, had you shown "sie", the first thought would have gone towards "sie" as in "she"…
Just use sentences that resolve those ambiguities.
