Example Sentences

Etymology

From Ancient Greek ἐννέα (ennéa, “nine”), for the ninth order of 10³; with the letter x added for the third term in a series running backwards through the alphabet (after zepto- and yocto-). The final o conforms to the final vowels of the SI series from micro- downwards.
