synovia

Note: The hypothesis that the synovia of Paracelsus is a compound of Greek syn- (see syn-) and Latin ovum "egg," on the assumption that synovial fluid resembles egg white, has no apparent foundation. Paracelsus assigned no color to the substance, which in his physiology is found in many places; moreover, the word is also spelled synophia in his texts, which does not suggest a connection with ovum.
