Hearty accord to mav's comment, One of the wonders of language for me is the ability to find new connections even in familiar material. I had a similar epiphany when dr. bill used a word, ithyphallic, unfamiliar to me. bartleby.com, gives the root and alternate form of that root. These were vigorous, seminal roots, and among their progeny are intriguing connections, some surprising.

I here cite only the striking fact that the words phallic and fool are linguistically related.

Ah, the deep wisdom embedded in our language!
