First Japanese Stack Exchange question :D
I'm reading a Japanese book and one of the chapter got me thinking.
The book wrote it like this:
How many pencils are there ? えんぴつはなんぼんですか。
Can we not not replace は with を ?
えんぴつ を なんぼんですか
を denotes a direct object in a sentence. は denotes the subject. Here, えんぴつ is the subject of the sentence, so it should have a は next to it.
