"This is my mother."

Translation: 这是我的妈妈。

[Nivkotzer]

I'm a bit confused, the explanation said whenever I use "this" or "that" I should add the measure word "gè", any help? Also maybe it's my bad ears but I hear the tone as "ge"

[MauroEzequ6]

Not necessary, 这是我的妈妈，这是我妈妈。this is my mother

[MatthewFic]

個 is a generic noun classifier. With people you wouldn't use it. It takes some practice to see the correct usage in many different contexts.

[ReddyBoi]

I think it is also fine to leave out the 的 when talking about one's own family members. 我妈妈，我弟弟，我哥哥, etc should all be fine to say as what I've learn from my classes.

[rodmir83]

I also think the same , I have heard 这个 我 的 妈妈

[RachaelBao]

D'oh. Possessive on family members is supposed to be optional.

[jame.s99]

the possessive particle can be dropped when talking about one's own family, this should be fixed

why is 这个我的妈妈。wrong?

[Anon341685]

You'd need the 是 to translate "is" but as for the 个, I wish I knew. I managed to leave it out, but gawd knows when these count/measure things have to be in, and when left out. Seems to be a random thing at present. As a general rule, if you've put it in, you're just wrong, but if you leave it out, then you're simply wrong. But I managed to buck the trend this time.

[GryTea]

You need 是 to emphasize "to be" in this case; without it, it's like 我 have several mothers or stepmothers or mothers-in-law, and 我 am specifying a specific one of them.
