The word 'tropological' is built upon the ancient Greek concept of tropos, meaning a "turn" or "change of direction." This evolved metaphorically to denote a "turn of phrase," giving us the modern sense of a "trope" or figure of speech. Combined with -logia (from logos, meaning "word" or "discourse"), it forms 'tropology,' the study or use of figurative language. The addition of the adjectival suffix -ical finalizes the term, which specifically entered English theological discourse to describe a method of biblical interpretation that seeks the moral meaning within the figurative or allegorical layers of the text. Thus, the literal "discourse on figurative turns" evolved into the abstract concept of interpreting metaphorical meaning for ethical instruction.
