Questions & Answers about tanin no kimochi o rikaisuru.

What does の do in 他人の気持ち?

の connects two nouns. Here it works like 's or of in English.

• 他人 = another person / other people
• 気持ち = feelings
• 他人の気持ち = other people's feelings or the feelings of others

So の shows that the feelings belong to, or are associated with, 他人.

Why is を used before 理解する?

を marks the direct object of the verb—the thing being understood.

In this sentence:

• 他人の気持ち = the thing being understood
• 理解する = to understand

So 他人の気持ちを理解する means to understand other people's feelings, with を showing what is being understood.

Why does the verb come at the end?
