A word for the day

For me, it is always a pleasure to learn a new word. It is particularly nice when it is one that I could probably use in “normal” life and fills a gap where I had no word before. Today’s word is:


The Wikipedia entry sums it up rather well:

Petrichor ( ˈpɛtrɪkɔːr ) is the earthy  scent  produced when  rain  falls on dry  soil . The word is constructed from  Greek   petra  (πέτρα), "rock", or petros (πέτρος), "stone", and  īchōr  (ἰχώρ), the fluid that flows in the veins of the gods in Greek mythology.

It seems that the smell is produced by Streptomyces bacteria that create geosmin. These bacteria are also used to create commercial antibiotics.

I particularly like the fact that word’s etymological origin is as interesting as the meaning.
