☆ understand 理解する
We can use “understand” in lots of different situations. For example, when you say you understand someone, it means you know what they are saying, you know what they mean: “I know you understand what I am talking about.” Or you can use it to say that you understand a language (or not!): “I couldn’t understand Spanish so I asked him to translate.”
You can also use understand when you want to say that you know how someone feels and why they are acting in a certain way:
My wife understands that when I am tired and hungry I get angry more easily!
It would be nice to have someone who really understood me.
You can use it to say that you know why something happens. “The doctors do not yet understand how the disease spreads.” Or “She was too young to understand what had happened.”
And finally, you can use it to say that you understand that something is true. “We understand that she is working on her second novel at the moment.” Or “I understand that you have heard the bad news.”
Can you use “understand” in all of these ways
