Words related to physician

physic (n.)

c. 1300, fysike, phisike, "a healing potion;" early 14c., "natural science;" mid-14c. "healthful regimen;" late 14c., "the art of healing, medical science or theory;" from Old French fisike "natural science, art of healing" (12c.) and directly from Latin physica (fem. singular of physicus) "study of nature," from Greek physikē (epistēmē) "(knowledge) of nature," from fem. of physikos "pertaining to nature," from physis "nature," from phyein "to bring forth, produce, make to grow" (related to phyton "growth, plant," phylē "tribe, race," phyma "a growth, tumor") from PIE root *bheue- "to be, exist, grow."

The English spelling with ph- is attested from late 14c. (see ph). The meaning "medicine that acts as a laxative" is from 1610s. The obsolete verb meaning "to dose with medicine, administer medical treatment to" is attested from late 14c. (phisiken).

Physics, in Aristotle, is the science of what the Greeks called 'phusis' (or 'physis'), a word which is translated "nature", but has not exactly the meaning which we attach to that word. ... 'Phusis' has to do with growth; one might say it is the 'nature' of an acorn to grow into an oak, and in that case one would be using the word in the Aristotelian sense. The 'nature' of a thing, Aristotle says, is its end, that for the sake of which it exists. [Bertrand Russell, "History of Western Philosophy"] 
1909, from German PH, introduced by S.P.L. Sörensen, from P, for German Potenz "potency, power" + H, symbol for the hydrogen ion that determines acidity or alkalinity.
dietician (n.)

"one who practices some theory of diet," 1845, from diet (n.1) on model of physician. Earlier was dietist (c. 1600).

mortician (n.)

1895, American English, coined from mortuary + -ician, as in physician.

An undertaker will no longer be known as an "undertaker and embalmer." In the future he will be known as the "mortician." This was decided on at the second day's meeting of the Funeral Directors' Association of Kentucky, which was held in Louisville. [The Medical Herald, July 1895]
physicist (n.)

"a student of physics," 1836, from physics + -ist. Coined by the Rev. William Whewell, English polymath, to denote a "cultivator of physics" as opposed to a physician.

As we cannot use physician for a cultivator of physics, I have called him a physicist. We need very much a name to describe a cultivator of science in general. I should incline to call him a Scientist. Thus we might say, that as an Artist is a Musician, Painter, or Poet, a Scientist is a Mathematician, Physicist, or Naturalist. [William Whewell, "The Philosophy of the Inductive Sciences," London, 1840]

It was used earlier in the sense of "one versed in the medical sciences" (1716) but this was rare and by 19c. was obsolete.
