Yes. 这个窗台 means this windowsill.

• 这 = this
• 个 = a very common measure word
• 窗台 = windowsill

In Chinese, demonstratives like this/that are often followed by a measure word before the noun:

• 这个人 = this person
• 这本书 = this book
• 这张桌子 = this table
• 这个窗台 = this windowsill

Even though English does not need a word like 个 here, Chinese usually does.

连...都... is a pattern used for emphasis. It often means something like:

• even...
• not even...
• to the extent that even...

In this sentence:

• 连一点儿阳光都没有

literally feels like:

• even a little sunlight, it doesn’t have

Natural English:

• There isn’t even a little sunlight on this windowsill.

This pattern highlights something surprising, extreme, or disappointing. It draws attention to the fact that even the smallest amount is absent.

Examples:

• 他连名字都不会写。 = He can’t even write his name.
• 我连一口水都没喝。 = I didn’t even drink a sip of water.

Great question. 都 does often mean all, but in the pattern 连...都..., it has a different function.

Here, 都 helps create emphasis with 连. Together they work like:

• even...
• not even...

So in this sentence, 都 does not mean all sunlight. It is part of the emphatic structure:

• 连一点儿阳光都没有 = there isn’t even a little sunlight

Think of 连 and 都 as a pair in this kind of sentence.

一点儿 means a little, a bit, or the slightest amount.

So:

• 一点儿阳光 = a little sunlight

In this sentence, it emphasizes that there is not even the smallest amount of sunlight.

A few notes:

• 一点 and 一点儿 are often very similar in meaning in everyday speech.
• In Standard Mandarin, 儿 is often added in northern-style speech, but usage varies by region.

Examples:

• 我想喝一点儿水。 = I want to drink a little water.
• 他一点儿也不累。 = He’s not tired at all.

Because 有 is normally negated with 没有, not 不.

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

So:

• 有阳光 = there is sunlight
• 没有阳光 = there is no sunlight

Using 不有 is not standard Mandarin.

This is one of the basic exceptions learners memorize:

• 是 → negated as 不是
• 有 → negated as 没有

Either way can help you understand it, but in natural English, there is no or there isn’t often sounds better.

Chinese sentence structure:

• 这个窗台 = this windowsill
• 连一点儿阳光都没有 = doesn’t have even a little sunlight

Natural English translations:

• This windowsill doesn’t even get any sunlight.
• There isn’t even a little sunlight on this windowsill.
• This windowsill has no sunlight at all.

So grammatically it looks like the windowsill doesn’t have sunlight, but in English we often phrase it more naturally as there is no sunlight on the windowsill or it doesn’t get sunlight.

阳光 specifically means sunlight.

• 阳 relates to the sun
• 光 means light

If you said just 光, that would usually mean light more generally, and the meaning could be broader or less specific. In this sentence, the point is specifically that the windowsill gets no sunlight.

So 阳光 is the natural choice.

窗台 means windowsill.

It refers to the flat ledge at the bottom of a window, often where people might place plants or objects. It is not the whole window.

So the sentence is specifically about that surface/ledge not getting sunlight.

Yes, it can be omitted, but the feeling changes.

With 连...都...:

• 这个窗台连一点儿阳光都没有。
• Strong emphasis: This windowsill doesn’t even have a little sunlight.

Without 连:

• 这个窗台一点儿阳光都没有。
• Still emphatic, and still very natural
• Means roughly: This windowsill doesn’t have any sunlight at all.

Without 连, the sentence is a bit less dramatic. With 连, the speaker more strongly highlights how extreme the lack of sunlight is.

Chinese usually places the focused item before 都 in the 连...都... pattern:

• 连一点儿阳光都没有

This structure is the standard emphatic pattern:

• 连 + focused item + 都 + verb/negative phrase

So:

• 连一点儿阳光都没有 is much more natural and idiomatic than
• 连都没有一点儿阳光 which is not correct.

You can think of it as:

1. introduce the thing being emphasized
2. mark it with 都
3. state what is true about it

It is written yìdiǎnr in pinyin here, showing erhua.

A few pronunciation notes:

• 一 is pronounced yí before a fourth tone in natural speech, so 一点儿 is commonly heard as yídiǎnr
• The 儿 is not usually pronounced like a full separate syllable er
• Instead, it colors the end of the previous syllable: diǎnr

So it sounds roughly like:

• yí-diǎnr

That said, pronunciation varies by region. In some accents, people may say something closer to 一点 without much 儿 sound.

By itself, it could be either, depending on context.

It can describe:

• a general fact: This windowsill never gets sunlight
• a current situation: Right now this windowsill isn’t getting any sunlight

Because Chinese does not always mark tense the way English does, context tells you whether it is a general statement or a specific moment.

In many contexts, this sentence sounds like a general observation about the location:

• This windowsill doesn’t get even a little sunlight.

Yes — that is a very natural translation.

Possible natural translations include:

• This windowsill doesn’t get any sunlight at all.
• This windowsill doesn’t even get a little sunlight.
• There isn’t even a bit of sunlight on this windowsill.

Because the meaning has already been given, the main thing to notice is that 连...都没有 adds emphasis, so translations with even or at all often capture the tone well.
