I'm sure of the intent of the above comment but I can think of more than
a few words that are "synonyms" ie two words with the same meaning.

I applaude your efforts at education. However, I am having a little

to speciation, at least *eventually*. I would guess that at the very
least, the word *species* might cause some discussion depending on
whether you are a lumper or a splitter.
