Questions & Answers about kono shashin wa shouko desu.
この means this and directly modifies a noun. Here it modifies 写真, so この写真 means this photo.
A key point is that この must be followed by a noun. You can say:
- この写真 = this photo
- この本 = this book
But you cannot use この by itself to mean this. If you want this on its own, you use これ.
- これは証拠です。 = This is evidence.
- この写真は証拠です。 = This photo is evidence.
Because この and これ have different jobs.
- この = this + noun
- これ = this by itself
So:
- この写真 = this photo
- これ = this
That is why これ写真 is incorrect.
