Kara & dakara "therefore", "so", "since" or "because"
The particle kara can indicate a reason or a cause. Kara comes after the phrase or clause which show a reason or cause.
There are two ways to use this pattern.
| 1. | Isogashii desu kara, paatii ni ikimasen. |
| Paatii ni ikimasen. Isogashii desu kara. |
| I'm not going to the party because I'm (too) busy. |
| 2. | Ashita shiken ga arimasu kara, konban benkyoo shimasu. |
| Konban benkyoo shimasu. Ashita shiken ga arimasu kara. |
| I have an exam tomorrow so I'll study tonight. |
When you make a statement after telling a reason, dakara is also common.
Dakara emphasizes the statement which shows a result, decision or judgment.
| 3. | Isogashii desu. Dakara, paatii ni ikimasen. |
| I'm (too) busy. So, I'm not going to the party. |
| 4. | Terebi ga kowaremashita. Dakara atarashii terebi o kaimasu. |
| My TV is broken. Therefore I'm going to buy a new TV. |
"Why" is dooshite or naze. Dooshite sounds softer than naze.
When you want to emphasize the reason, you can start your sentence with Nazenara.
| 5. | Q | : | Dooshite Chuugoku ni ikimasu ka? |
| A | : | (Nazenara) Pekin de kaigi ga arimasu kara. |
| Q | : | Why are you going to China? |
