I can't believe how unreasoning some people can be during arguments.

Right? It's like they aren't even listening to logic.

It makes discussions really frustrating when that happens.

Root Explanation

Unreasoning → It is formed from "un-" (meaning not) and "reason" (from Latin "ratio", meaning reason or rational thought) and the suffix "-ing" (indicating the action or process). The word "unreasoning" describes a state of not using reason or rational thought, often implying a lack of logic or understanding.

Memory Tip

Think of 'not' ('un-') using 'reason' — that's why unreasoning means acting without rational thought.
