A Closer look at を
Pronounced o but written in Japanese as wo. Simply put, を is the 'direct object marker or particle' which indicates the previous word is the direct object. There are cases when the English would not consider it a direct object, though. Learn some examples and give it a try. This particle is one of the easier ones...
watashi wa ringo o tabemashita.
I ate an apple. (apple is the を)
ongaku o kikitai desu.
I want to listen to music. (music is the を)
terebi o kau tsumori desu .
I intend to buy a TV. (tsumori means'intend to'; TV is the を)
