Okay, I guess I should have put my usual ;0) on that one; I didn't because I was making a funny and trying not to be so obvious like an ignorant LOLer...

welcome, M!

here's what came up in my Apple dictionary:

parenteral |pəˈrentərəl|
adjective Medicine
administered or occurring elsewhere in the body than the mouth and alimentary canal : parenteral nutrition. Often contrasted with enteral .
DERIVATIVES
parenterally adverb
ORIGIN early 20th cent.: from para- 1 [beside] + Greek enteron ‘intestine’ + -al .

The word in bold, especially, reminded me of "etaoin", and that's where the word (I made up) came from. The closest real word seems to be "parenetioal", as helpfully suggested by Myr... Sorry for the confusion (okay, not really... LOL!!!) ;0)
