A definition of the the word Serpent

The English word Serpent has been derived from the Latin serpens with the basic root of SRP, which through sound shifts within the Indo-European language, also incorporates SRB, SRF, SRPH, and SRV. For example the following words in English with this root:

SeRVe – to perform a duty.

SuRVive – to outlive; have a long life.

SuRVey – to examine, or dignose.

SyRuP – a term used in early medicine.

SuRPlice – a white covering, used in Druid and Christian ceremonies, cognate with the white overall used in hospitals.

The closest association is with SERAPH, one of a group of angels known in plural as SERAPHIM. The Hebrew word rapha meant healer, surgeon or doctor. The term Ser (Sir) meant a higher being or guardian angel; hence a reasonable deduction that the SERAPHIM were a corps of medical angels.

The Egyptian god SERAPHIS had medical associations; his temple at Memphis which contained a hospital, was called a SERAPEUM.

Additionally, SERAPION was an eminent physician of Alexandria in the third century A.D., a name derived from his profession.

It must be acknowledged that the term SERPENT had wider associations with wisdom and wise men or women.
