Another popular etymology is the hypothetical Greek word ἀντίμόνος antimonos , " against aloneness " , explained as " not found as metal " , or " not found unalloyed " . Lippmann conjectured a hypothetical Greek word ανθήμόνιον anthemonion , which would mean " floret " , and cite several examples of related Greek words ( but not that one ) which describe chemical or biological efflorescence .
