English may be the biggest language in the world but we're still missing an awful lot of words.
What's the English for the back of the knee?
For a mouth-watering scent?
For a piece of food stuck between the teeth?
I'm afraid I can't help you with any of those (and how impoverished our world is by their absence) but how about inion?
Yes, the word reminded me of onion, too, and in some ways it's linked in meaning because the inion the Lowestoft of the cranium, that is, basically, the bit of the head that sticks out the most at the back.
It's great fun spotting these. (It's easiest with bald people.)
Yes, that's right: there's nothing like knowing your inions.

Spot the Frippet: inion. This is a word used in craniometry (the measurement of skulls. Craniometry been used over the years to prove all sorts of dodgy theories, but today is used quite respectably in archaeology and medicine). Inion is Greek for the back of the head.
