Etymology
The word "praseodymium" comes from the Greek words "prasios" (leek-green) and "didymos" (twin). The element was named after its green salts, which were found to be chemically similar to those of didymium, a now-obsolete name for the lanthanide element neodymium.
The first recorded use of the word "praseodymium" in English was in 1885.
