What does petrichor mean?
Petrichor names the distinctive earthy smell that follows rain, particularly when the rain reaches dry soil or pavement. The word is especially evocative after a period of dry weather, when the scent can seem sudden, vivid, and memorable. Although it refers to a natural odor, petrichor is also used figuratively to describe an atmosphere of freshness, comfort, nostalgia, or renewal. Its unusual sound and precise meaning make it especially effective in descriptive writing, poetry, journalism, and captions. The term was coined in the mid-20th century from Greek roots associated with stone and the blood of the gods, giving an ordinary sensory experience a memorable, elevated name. It is now familiar in British and American English, though it remains more literary than everyday vocabulary.

Etymology of petrichor
Petrichor was coined in 1964 by Australian television announcer and writer Thomas Ian Maxwell for his book The Smell of Rain. He formed it from the Greek words petra, meaning “stone” or “rock,” and ichor, the fluid said to flow in the veins of the gods. English words such as petrify, petrology, and petrous share the stone-related root, while ichor is the second element from which the name was directly constructed.
How petrichor is actually used
Petrichor is literary and evocative rather than strictly technical. It is usually treated as a mass noun and is especially common in poetic, descriptive, and nostalgic contexts.
