so, I will give you just one, fairly disturbing one, that I learned tonight.
The word is "fetotome"
Let's use our knowledge of word roots, prefixes, suffixes, and combining forms to dissect (no pun intended) this simple word.
-tome is a word element meaning "an instrument for cutting"
feto- is a combining form meaning "fetus", infant, baby, whatever you want to call it.
So, a fetotome is, what? An instrument for cutting fetuses.
Let me give you an actual definition (taken from Saunders Comprehensive Veterinary Dictionary):
"fetotome an instrument designed for use in cows and mares for the purpose of dissecting a dead fetus in utero when normal delivery is impossible and cesarean section inadvisable. There are a number of special instruments all based on fetotomy [note: this is the dissection of a dead fetus in utero] wire saws passed through metal tubes about 3 ft long. These are threaded external to the cow by passing the wire saw out of the end of one tube, into the uterus and around the part to be amputated, out of the uterus and into the other tube. The two ends of the saw are brought out of the far ends of the tubes and special handles are attached. The tubes are inserted into the uterus and pushed hard up against the skin. Rapid see-sawing with the saw completes the task."

Yeah, saw a picture of a fetotomed colt tonight in a presentation. Not so neat...
