Express two simultaneous actions.
The rule
Base of ます + ながら + main action. The subject of both actions is usually the same. The main action is at the end.
Examples
音楽を聞きながら勉強します。
I study listening to music.
Remember
- ます base without ます + ながら + main action.
- The subject of both actions is normally the same.
In everyday life
音楽を聞きながら勉強します。
I study listening to music.
歩きながら電話しないでください。
Don't call when you're walking.
Common mistake
The action after ながら is usually the main action; do not confuse with a succession of shares.
