Is there a word for . . . ?

One of my favourite aromas (another being geranium leaves) is the one that rises from dry ground when it starts to rain. How would I describe it? No idea. Until now, that is. Because I’ve just discovered a word invented for this very purpose: petrichor.

Arriving like an interesting latecomer at a party, petrichor wasn’t coined until the 1960s. Oxford Dictionaries explains that the word is a “blend of petro- ‘relating to rocks’ (the smell is believed to be caused by a liquid mixture of organic compounds which collects in the ground) and ichor.”

Ichor? I know, one thing always leads to another. But I’m very glad it did in this case because, as Oxford Dictionaries explains, ichor is “the fluid which flows like blood in the veins of the gods.” How poetic!

Anyway, if you want to find out a bit more about this word, the people who coined it and the science behind it, here’s the Wikipedia article, plus a really interesting piece in Scientific American.
