hemophilia n.

word-forming element in pathology meaning "condition of the blood," Modern Latin combining form of Greek haima (genitive haimatos) "blood," a word of no established etymology (replacing the usual IE word, represented in Greek by ear; possibly from uncertain PIE root *sei- "to drip" (compare Old High German seim "virgin honey," Welsh hufen), but according to Beekes this proposal "cannot explain the Greek vocalism."

word-forming element meaning "friendship, fondness, tendency toward," and in recent use "abnormal attraction to," from Greek philia "affection," from philos "loving," which is of uncertain origin. Related: -philic.
