the word 'zoology' is a modern formation from greek components. the root 'zoo-' derives from the ancient greek 'zōion', meaning 'animal' or 'living being', which is itself of uncertain proto-indo-european origin, possibly linked to concepts of life. the suffix '-logy' comes from greek '-logia', denoting 'the study of' or 'a discourse', originating from 'logos' meaning 'word, reason, account'. combined in new latin as 'zoologia', the term literally means 'the study of animals', a meaning that has remained consistent as it entered english in the 17th century to name the scientific discipline.

Structure: zoo (animal) + logy (study of) - zoo: from greek 'zōion' meaning 'animal, living being'. serves as the root/base meaning 'animal'. - logy: from greek '-logia' meaning 'study of, discourse'. serves as a suffix denoting a branch of knowledge.
