Emerald

So, I chose this word tonight/morning because in few days the newest edition to my family will be dubbed Emerald. To match her sister Diamond, of course. Although my sister did not ask my opinion on these unusual name choices I am secretly thrilled with them. I mean, I am their Aunt Crystal. :) So, to honor this little one I've decided to dissect her name. Strange way of honoring her I guess, but eh, such is life.
As most of you already know the word emerald is usually in reference to the stone. The OED defines it as:
" 1. A precious stone of bright green colour; in mod. use exclusively applied to a variety of the Beryl species (see BERYL n. 2), found chiefly in S. America, Siberia, and India."
Or:
"3. transf. as name of its colour; = emerald-green."
And, to my surprise, it can also be defined as:
" 4. Printing. The name of the size of type larger than nonpareil and smaller than minion."

This last one is definitely new to me. To keep things neat and simple I am going to use the AHD's etymological history of emerald. According to the AHD emerald originated in the Greek word smaragdos, then preceded to Latin in the form smaragdus (not much change there). It then progressed to Med. Lat. in esmeralda, esmeralus (which looks much closer to our word). From Med Lat it went on through OFr then to ME as emeraude. That's a bit complicated but I like that the word is founded in Greek. :) (The word diamond is rooted in Latin and crystal is from Greek, too. Just in case you were wondering.)
