Etymology: "Pathohistologist" is built from "pathohistology" plus the suffix "-ist", which marks a person who practises or specialises in a field. Pathohistology is itself a compound of "patho-", from Greek "pathos" meaning suffering or disease, and "histology", the study of tissues, which draws on Greek "histos" meaning web or tissue. Put together, the word names a specialist who examines diseased tissue under the microscope. The formation is typical of modern scientific vocabulary, where Greek elements are combined to name a new discipline and then a practitioner of it. The "-ist" ending follows the same pattern as "pathologist" and "histologist", so a reader who knows those words can work out this one without a dictionary.
