连...都... is a common pattern meaning even..., often with surprise, disappointment, or emphasis.

So:

这个花盆连排水孔都没有。

means something like:

This flowerpot doesn't even have a drainage hole.

Here, 连 introduces the thing being emphasized, and 都 helps complete that emphatic structure.

A very literal breakdown would be:

• 这个花盆 = this flowerpot
• 连排水孔都 = even a drainage hole
• 没有 = does not have

So the speaker is saying that the flowerpot lacks something very basic.

Yes, 都 often means all, but in the pattern 连...都..., it does not mean all in the usual sense.

Instead, it works as part of the fixed emphasis pattern:

• 连...都...
• 连...也...

Both can mean even...

So in this sentence, 都 is not really being translated as all. It is helping express the idea:

even a drainage hole ... doesn't have one

This is a very common thing in Chinese: a word has one basic meaning, but in certain patterns it has a more grammatical function.

Yes. You can say:

这个花盆连排水孔也没有。

This also means This flowerpot doesn't even have a drainage hole.

Both 连...都... and 连...也... are used. In many cases they are very similar.

Very roughly:

• 连...都... can sound a bit stronger or more standard in this kind of emphasis
• 连...也... is also natural and common

For learners, the safest thing is to recognize both patterns as meaning even...

Normally, yes, Chinese often places the object after the verb:

• 这个花盆没有排水孔。
• This flowerpot doesn't have a drainage hole.

That is the plain, neutral version.

But with 连...都..., the item being emphasized is moved forward:

• 这个花盆连排水孔都没有。

This fronting highlights 排水孔 as something surprising to lack.

So the word order changes because of the emphasis pattern, not because the basic grammar of 没有 is different.

The difference is mainly emphasis.

• 这个花盆没有排水孔。
  = This flowerpot doesn't have a drainage hole.
  This is neutral and factual.

• 这个花盆连排水孔都没有。
  = This flowerpot doesn't even have a drainage hole.
  This sounds more surprised, critical, or emphatic.

So the second sentence suggests that a drainage hole is such a basic thing that its absence is noteworthy.

In modern Mandarin, 有 is normally negated with 没有, not 不.

So:

• 有 = to have / there is
• 没有 = to not have / there is not

You would say:

• 我有钱。 = I have money.
• 我没有钱。 = I don't have money.

Not:

• 我不有钱。 ❌

So in this sentence:

• 没有 = does not have

This is one of those patterns that learners simply need to memorize:
有 → 没有 for negation.

Yes, and that is perfectly natural.

You could say:

• 这个花盆连排水孔都没有。
• 这个花盆连一个排水孔都没有。
• 这个花盆连个排水孔都没有。

All of these can work.

The differences are small:

• 连排水孔都没有 = even a drainage hole / even drainage holes
• 连一个排水孔都没有 = doesn't even have a single drainage hole
• 连个排水孔都没有 = a very common colloquial version of the same idea

Adding 一个 or 个 makes the meaning of not even one more explicit.

排水孔 means drainage hole.

It is made up of:

• 排水 = to drain water
• 孔 = hole

So literally it is a water-draining hole.

This is a good example of how Chinese often builds nouns by combining smaller meaningful parts.

In standard Mandarin, when 这 modifies a noun directly, it usually takes a measure word:

• 这个花盆 = this flowerpot

Structure:

• 这 = this
• 个 = measure word
• 花盆 = flowerpot

So 这个花盆 is the normal form.

Sometimes in casual speech or certain styles, people may shorten things, but for learners, 这 + measure word + noun is the rule to follow.

Yes. 个 is completely fine here.

Even though Chinese nouns can have more specific measure words, 个 is the most general and very commonly used one. For many everyday objects, especially in normal conversation, 个 is acceptable.

So:

• 这个花盆 = this flowerpot

is natural and standard.

No. 连 has more than one use.

A learner may first meet 连 as a verb meaning to connect or to join. But here it is not a verb. Here it is part of the grammar pattern 连...都/也..., meaning even.

So compare:

• 把这两条线连起来。 = Connect these two wires.
  Here 连 is a verb.

• 这个花盆连排水孔都没有。 = This flowerpot doesn't even have a drainage hole.
  Here 连 is an emphasis marker.

Same word, different function.

Yes, very often it does.

Because 连...都没有 highlights the absence of something basic or expected, it can sound like:

• surprise
• disappointment
• criticism
• complaint

So depending on context, this sentence might suggest:

• What kind of flowerpot is this? It doesn't even have a drainage hole.

Of course, tone of voice and situation matter, but the grammar itself often carries that feeling of this is surprisingly inadequate.

It is written zhège, and in natural speech it is usually pronounced as zhè ge.

A few useful points:

• 这 is fourth tone: zhè
• 个 here is usually neutral tone: ge

So it sounds like:

• zhè ge huāpén lián páishuǐkǒng dōu méiyǒu

Learners sometimes over-stress 个, but in everyday speech it is usually light.

Yes, if the context already makes the subject clear.

For example, someone is holding the pot and says:

• 连排水孔都没有。

That can mean:

It doesn't even have a drainage hole.

Chinese often omits the subject when it is obvious from context. But when you want to clearly identify the thing being talked about, 这个花盆 is included.

It is basically using 没有 in the sense of doesn't have.

In Chinese, 有 / 没有 can express both:

• existence: there is / there isn't
• possession: have / don't have

Here, for natural English, we translate it as possession:

• This flowerpot doesn't have a drainage hole.

But the underlying Chinese idea is still closely related to there is not a drainage hole on/in this flowerpot. Chinese often does not sharply separate those two ideas the way English does.
