Noun

rho (plural rhos)

1. The seventeenth letter of the Modern Greek and Classical alphabets and the nineteenth letter of Old and Ancient.
   • 2022, R. F. Kuang, Babel, HarperVoyager, page 25:

     Greek was an exercise in making the familiar strange. Its alphabet mapped onto the Roman alphabet, but only partly so, and often letters did not sound how they looked – a rho (Ρ) was not a P, and an eta (Η) was not an H.

2. (finance) The sensitivity of the option value to the risk-free interest rate.
