Etymology: "Cetologist" is a plain formation: it combines "cetology", the study of whales and related marine mammals, with the suffix "-ist", which denotes a person who practises or specialises in a field. The root of "cetology" is the Greek "ketos", meaning a large sea creature or whale, so a cetologist is literally someone who studies "ketos" in the scientific sense of the word. The suffix does most of the work in the noun's shape. Attaching "-ist" to a field of study is a common English pattern, as in "biologist" or "geologist", and "cetologist" follows the same model. The word's meaning therefore comes straight from its two parts, with no change of sense along the way.

Synonyms: whale researcher, marine mammalogist, oceanographer, marine biologist, biologist
