Quick Answer

Petrichor means the smell of earth after rain. It is a noun. You say it like this: PET-rih-kor. This word describes that fresh, earthy scent you notice when rain hits dry ground. Scientists say this smell comes from oils in plants and a compound made by soil bacteria. Petrichor is not the smell of rain itself. It is the smell rain releases from the earth. Writers love this word because it makes weather descriptions feel more real and poetic.

Origin

The word petrichor is fairly young. Two scientists made it up in 1964. Their names were Isabel Bear and Richard Thomas. They combined two Greek words to build it. The first part, petra, means stone. The second part, ichor, means the fluid that flows through the veins of gods in old Greek myths. So petrichor literally means the blood of stone. The scientists studied why rain makes that special earthy smell. They found that plant oils build up on rocks and soil during dry spells. When rain falls, it releases these oils into the air. This is how the smell of petrichor gets its magic.
