Questions & Answers about zhè jiùshì kèfúdiànhuà.

Why is 这 used by itself here? Why not 这个?

In this sentence, 这 works as a pronoun meaning this.

So:

• 这就是客服电话。 = This is the customer service phone number.

You do not need 个 here, because 这 is not directly modifying a noun right after it. It is standing alone as this.

Compare:

• 这是客服电话。 = This is the customer service phone number.
• 这个电话是客服电话。 = This phone is the customer service phone number/line.

A simple way to think about it:

• 这 = this as a standalone pronoun
• 这个 + noun = this + noun

Both 这 and 这个 can sometimes appear in speech, but 这就是... is very natural here.

What does 就是 mean here? Why not just 是?
