Pronounced: SHUN-pike, noun/verb
Notes: I don’t remember running across this word, and couldn’t guess the meaning, but I felt kind of silly when I looked it up; the meaning is straightforward — and with that hint, maybe you’ll get it.
We know the word intestine as a noun (the lower part of the alimentary canal), but as an adjective, it means internal, and specifically, “of or relating to the internal affairs of a state or country”; a synonym for “civil”.
Background / Comments
The word comes from Latin intestinus (internal), which itself comes from intus (within). Thus, we can note that there is quite a difference between “intestinal rumblings” and “intestine rumblings” (heh).
The word came into English in the 1400s
