-nagara ( Genki II Chapter 18)


You can connect two verbs with ながら to say that the two actions are preformed at the same time. ながら follows a verb stem. The second, which goes after ながら, can be in any form.


I always study Japanese while listening to music.


Takeshi is doing laundry singing a song.

Note the two verbs must be preformed by the same person.
