My finger slipped in my last post - what I meant to say was that with irr being an eroded in, "irrecognizable" is really a way of writing "inrecognizable."

(And I suppose the dash in that last sentence could be seen as taking the place of a semicolon. Couldn't have been a comma - I suppose it could have been a full stop, at a stretch. I prefer a dash. Looks better on the page.)
