有的是【yǒudeshì】

有的是 says there's plenty of something – so much that there's no need to worry, hurry or hold back. It goes before a bare noun, and belongs to speech and relaxed writing.

The noun can come first, as the topic, with 有的是 closing the sentence. This order is common when reassuring someone.

A place can be the subject: "this place has plenty of X".

有的是 or 有的 + 是

有的 "some" followed by 是 "are" is a different thing, and sets one group against another: 有的是学生，有的是老师 "some are students, some are teachers". 有的是 "plenty" isn't paired with a second 有的.

Mistakes

有的是 already means "a lot", so 很多 after it says it twice.

• × 我有的是很多时间 → 我有的是时间

It has no negative. 我没有的是时间 is a different sentence: "what I don't have is time".
