Well i *did LIU, acksherly, which is why i added the "feather-like" qualifier to the definition I quoted, lest anyone *else not know the word.

What I was trying to ask in my own inimatatibly©* fumbling way wasn't "what does 'pinnate' mean" but rather "does everyone on the planet know this word except for me?".

But thanks for the link an' the purty pitchers

*wasn't that the word that of troy coined, which hyla commented on?
