Every day, a rare word arrives with five definitions. Four are real. One was masterfully fabricated to sound exactly like the others. You have three accusations to find it.
AThe pleasant smell that accompanies the first rain after a long dry period. — OED

CFrom Greek petra (stone) and ichor, the fluid said to flow in the veins of gods. — Etymology note
DThe thin film of organic compounds deposited on dry surfaces before rainfall. — Chemistry Rev.
