Some students asked what&39;s the difference between the words,&34;rational&34;,&34;sensible&34; and &34;reasonable”?

It is a difficult question. These three words are very similar in meaning, and in many situations, they can mean almost the same thing, but there are some differences.

Today, I&39;ll try to give you a simple answer.

---

• “Rational”usually means based on clear thought and reason.
• Looking at facts in a very logical and intelligent way and making a decision based on knowledge. It&39;s quite objective.

---

• “Sensible” means useful and practical.
• If you make a sensible decision,you think about how easy it is to do something, how suitable a decision or a suggestion is. Sensible involves how you feel about doing something, not just facts, so sensible is more subjective.

---

• “Reasonable” is fair or acceptable.
• So we often use reasonable when we&39;re talking about making a deal or some kind of contract. Reasonable usually means it&39;s fair to both sides maybe the seller and the buyer, both people in the discussion.

In sum,

• Rational -a decision based on clear facts and objective knowledge
• Reasonable -when something is fair or acceptable.
• Sensible -when it just feels right.
