Thank you for those insights. I think 'modus operans' should be 'modus operandus' or operandi though, because it's not a participle, but a gerund.

Please apologize, I can't help it. In fact, I would've become a paid subscriber to do this, if comments were deactivated. :D I was gonna say a word or two about my latin teacher, but I get scared just thinking about him.
