Her ratiocinative approach helped solve the complex problem efficiently.
Ratiocinative → It is formed from "ratio" (from Latin *ratio*, meaning reason or calculation) and "-cinate" (from Latin *cinate*, meaning to move or to cause to move). The word describes the process of reasoning or thinking logically, as it combines the idea of reasoning with the action of engaging in that reasoning.
Think of 'reason' ('ratio') and the action of 'moving' or 'engaging' in thought ('-cinate') — this helps you remember that 'ratiocinative' relates to the act of reasoning.
