pathologist

Etymology

It is formed from English patho- + -logist, after pathology;^[1] Etymonline and the Shorter Oxford analyse it as pathology with the suffix -ist.^[2][3] Pathology is from French pathologie and New Latin pathologia (“study of disease”),^[2][1] formed from Ancient Greek πάθος (páthos, “suffering”) and -λογία (-logía, “study”).^[2][1] Etymonline notes that the Greek compound itself meant the study of the passions.^[2] Johnson (1755) derived the word from the Greek words for suffering and for speaking.^[4]

Earliest recorded meaning

A person who studies or writes about disease: 1650, in Walter Charleton's translation of J. B. van Helmont.^[1][5] Etymonline dates it to the 1640s.^[2]

Semantic evolution

For two centuries a pathologist was anyone versed in the nature of diseases or who wrote on them;^[1][2] Johnson (1755) defined him as "one who treats of pathology".^[1][4][2] A note in The Lancet (1971), quoted by the OED, describes the later British shift: by the early 20th century the word was already used chiefly of doctors working in laboratory medicine, and by the 1930s, used alone, it was increasingly limited to specialists in morbid anatomy and histopathology, while other laboratory doctors called themselves "clinical pathologists".^[1] The National Health Service and the Royal College of Pathologists later widened it again, the College wishing to include biochemists who are not doctors.^[1] Today the word usually means a specialist who examines samples of body tissue for diagnosis or for forensic purposes.^[3][1][5]
