You have already learned some functions of Japanese particle de (で) in basic lesson 16. This lesson will introduce more functions of it.
The first one will be to use particle de (で) to ask if something is alright. The sentence pattern is as follow...
Noun で いいですか
Noun de ii desu ka
Meaning: Is Noun alright for you?
Lets's look at some examples on how the Japanese particle de (で) works in this situation.
1. Assuming that you are invited to a party tomorrow. You are not sure what is the required attire. You can ask the host the following...
2. Your colleague lost his wallet on the way to the office. When he meet you at the office he asks you for help to lend him some money. You are not sure how much you should lend him and ask him...
3. Your friend came to your house to visit you. You want to serve him drink but are not sure what is suitable for him. You can ask him the following...
In all the above 3 examples, Japanese particle de (で) is being used because you are not sure what the party host, your colleague and your friend wants. You use で to make your tone soft and not sound so pushy.
Some students might have used particle ga (が) in the above 3 examples. However, using が (ga) in this case has a different meaning.
Noun が いいです (Noun ga ii desu) means you prefer Noun. For example...
In using particle ga (が), you are choosing the best choice among some options. If you use が (ga) instead of で (de) in the previous 3 examples, the meanings are different.
1. You ask the party host about the attire.
2. Your colleague wants to borrow money from you.
3. You want to serve drink to your friend.
How do you answer when you were asked the same questions in the above examples? In example 3, let's say it's you who were asked if you are alright with coffee. How do you answer?
Of course in conversation, you can simply answer "はい、いいです (hai, ii desu)". But in a full sentence, if you want to answer politely and properly, you should answer...
You can also use particle de (で) to mention something happened when you were at certain age. The sentence pattern is simple...
Meaning: At the age of ~
For example, you can use で (de) to indicate what happened to Mr Yamada in his whole life.
It's not limited to the past events. Japanese Particle de (で) can also be used for things which will happen in the future. For example, if you intend to get married at the age of 27, you can say the following...
