Sam: I almost wish I hadn't asked. But de verdad, I'm glad I did because I got an education and a half in the process!!!!! Like you, I have an authentic long haired dictionary, and this morning that dictionary had a companion, so I queried las dos: They agree that sobrevivir (verb) and la supervivencia (noun) are the way to go in Costa Rica. I'd say that they "actually know". Not that they are linguistic authorities, but they sure as heck speak the lingo better than any gringo, and when 2 hermosas muchachas agree, well, who am I to argue? It's beyond my paygrade, too.
More fascinating to me, perhaps metaphysically, was your allusion to the Spanish nuns spanking me with their ruler. Now, just how might they do this, but more profoundly, who is their ruler? Would it be His Royal Majesty King Felipe VI, El Rey de España? I tend to think not, more likely it would be His Holiness el Papa Francisco? That's quite plausible, but maybe they would go all the way to the top, to Our Lord and Savior hisself!!!!! I shudder to contemplate how any of these spankings might be administered, and it's better to change the subject.
With or without your double PhD, or your diccionario con pelo largo you can collect a drink or two here in friendly San Ramon any time Sam...thanks for the explicación, no longer a conundrum, just one of those little curiosities that makes Spanish so interesting (and elusive).....joe
