I simply love it when I stumble upon an interesting new word!
This one came about by accident when having a chat in my local hostelry. The day before I had been sitting at a table in the back, writing in my notebook. There was a sudden change in the atmosphere and I knew it was raining. The smell was unmistakable and a glance out of the window only confirmed what I already knew as the pour began.
A day or so later at the same venue, I was chatting with a good friend about music that she might like and remembered an album by Mortiis, The Smell of Rain, which had been a favourite of mine when it came out a few years ago.
I duly Googled the name but was met by the following revelation from Wikipedia as the first result:
Petrichor (/ˈpɛtrɪkɔːr/) is the earthy scent produced when rain falls on dry soil. The word is constructed from Greek πέτρα petra, meaning “stone”, and ἰχώρ īchōr, the fluid that flows in the veins of the gods in Greek mythology.
I love that something like this actually has a name – and one with such an exotic etymology too.
