I bet this is related to tenacious. Maybe that will help me separate it from all of those other per-par-pen words:
pernicious
parsimonious
penurious
perspicacious
persnickety (well, that one's easy) - hey, I'm just finding that pernickety is a word! What the heck? Oh, it means the same as persnickety, just not the "colloquial" meaning. Hmm.
impecunious
