Information
is a particle that is often thought of as meaning ‘and’ in English, which is quite often how it can be translated. In a broader sense, simply shows that there is a relationship of ‘compilation’ between (A) and (B). That relationship could be existing together (translated as ‘and’), or performing an action together (translated as ‘with’).

  • 彼女(かのじょ)食(た)べ
    I eat with my girlfriend.
is required after every noun that it is grouped with. However, the last in a sentence will often be omitted, if there are several.
  • 消(け)しゴムペン鉛筆(えんぴつ)
    There is an eraser, pen, and a pencil too.
In this example, we can see that the last noun in the group (pencil) does not require the particle , although it is considered more correct to have it. In conversation, the last will almost always be omitted.
