Exactly.. they might not even speak English (or any other language that EQ has been published in :D ) as we know it, and that is't only for storytelling simplification things are as they are, but with hints of misunderstanding here and there.. or how to put it.. I suppose this'd be like comparing LOTR and Quenya and all those other languages Tolkien put a huge effort in to create that the elves and others spoke, and English just happened to be the language the story itself was mostly retold in, set as a base.. but the Pinis do have Elven words and names puzzled in, so far :)
I'm not sure if this is established, but my take on the whole wolf-sendings is that they are giving out an image, not a word. Or, maybe they do send out a word since the wolves are also descendants of Timmain. But since they are mostly wolf, they are only able to give out a word, or again, an image.
