I am finding what I understand of this interesting, and I do enjoy a bit of linguistics, but perhaps I shouldn't have encouraged it a few pages ago. Carry on though.
(Raak) With "embolden" and "enliven" it would seem that in the past someone has done just that. I don't think the rules are particularly well-defined. (nights) Yep, we're a bunch of swivel-eyed fundamentalists. In the beginning was the Word. AND THE WORD SHALL BE SPELT PROPERLY. :-)
Is there an opposite for "enlarge" which has the same pattern? There doesn't seem to be an "ensmall" or "enlittle" (although there is "belittle" but then where's the "belarge"?) - the closest in meaning is probably "shrink," which seems to have no connection with any words meaning "small" whatsoever.
