KK: /rɛtrəˈdɪktɪv/
Relating to the act of inferring past events based on present evidence or knowledge.
The scientist used a retrodictive approach to understand the historical climate changes.
Retrodictive → It is formed from "retro-" (meaning backward) and "dict" (from Latin "dicere", meaning to say or declare) and the suffix "-ive" (meaning having the nature of). The word "retrodictive" refers to the nature of declaring or predicting something based on past events or data.
Think of looking 'backward' ('retro-') to 'declare' or 'say' ('dicere') something about the past — that's what retrodictive means.
