Use of ni or wa for " I always eat with my older brother on monday"


In my textbooks solution it says

> getsuyoubi ha itsumo ani to isshoni tabemasu

I thought it would be

> getsuyoubi ni

Thank you in advance




So, first of all, the sentence （私は）月曜日にいつも兄と一緒に食べます。 is grammatically totally
fine and would be comprehended in the context you give. This would probably
best structurally translate as

> "I usually/always eat with my brother on Mondays"

However, partly because Japanese is a pronoun-drop language, and partly
because of the situation -- where the speaker has been asked about going for
pizza (presumably on a Monday) -- 月曜日 **は** いつも兄と一緒に食べます might well be
preferable here.

The reason for that is that he's focusing on the concept of Monday, so it
makes sense to make it the topic/discourse of the conversation. In comparison
to the above sentence, you'll thus get a structural translation of something
closer to

> "On Mondays, I usually/always eat with my brother".

Using は thus makes it a bit clearer that it's the pizza invitation **being on
a Monday** that is the issue as to why he can't go, which is appropriate for
this context.

Hope that helps.
