<p>After some reflection, I believe <strong>the underlying grammar</strong> of the <em>topic - comment</em> <code>Noun - Adj + 的</code> sentence is:</p>
<blockquote>
<p><code>Noun - (是) + Adj + 的</code></p>
<p>Noun - (is) an Adj one.</p>
</blockquote>
<p><strong>So the verb <code>是</code> is omitted, the predicate is <code>(是) + Adj + 的</code> and the subject is <code>Noun</code>.</strong> This is because <code>Adj + 的</code> <em>nominalizes</em> the <code>Adj</code>, and we still need a verb. (If anyone can provide an alternative explanation, I would be interested to hear it).</p>
<p>In the example:</p>
<blockquote>
<p>他的儿子 - 高的。</p>
<p>His son - (is) a tall one.</p>
</blockquote>
<hr />
<p>There are two <em>alternative</em> ways to express it:</p>
<ol>
<li><p><strong>Explicitly with 是</strong>:</p>
<blockquote>
<p>他的儿子 是 高的。</p>
<p>His son <em>is</em> a tall one.</p>
</blockquote>
<p>Although this introduces some emphasis on the adjective (<a href="https://chinese.stackexchange.com/a/40001/25265">@dan, @blackgreen</a>).</p>
</li>
<li><p><strong><code>Noun + (Adv of degree) + Adj</code> structure</strong>:</p>
<blockquote>
<p>他的儿子很高。</p>
<p>His son is tall.</p>
</blockquote>
</li>
</ol>
<hr />
<p>A <em>different grammatical</em> expression is the <strong>noun phrase <code>Adj + 的 + Noun</code></strong> (@fefe, @dan):</p>
<blockquote>
<p>他的高的儿子。</p>
<p>His tall son.</p>
</blockquote>
<hr />
<p><strong>A reduplication of adjectives <code>Adj + Adj</code> is still an <code>Adj</code></strong>, so all the previous grammatical considerations hold.</p>
<p>However, as pointed by <a href="https://chinese.stackexchange.com/a/40002/25265">@dan</a>, a reduplication of the adjective has a different semantic meaning: the adjective becomes more <em>vivid, cutie, lively, etc.</em></p>

Stilted means incorrect though? Because maybe it is not the most used expression but could be useful for the explanation (if you can think of some better example).

# How "Noun + Adj + Adj + 的" (reduplication of adjectives) is grammatically equivalent to "Noun + (Adv of degree) + Adj"?

(Asked by: username_0 on 2020-07-10)

This question is motivated from [Why 的 in reduplication of adjectives "Noun + Adj + Adj + 的"?](https://chinese.stackexchange.com/q/39997/25265). In the answers, it was argued that the *reduplication of adjectives* structure:

1. > `Noun + Adj + Adj + 的`
   >
   > Ex: 他的儿子高高的。

is indeed a *topic - comment structure*:

> `Noun - Adj + Adj + 的`
>
> Ex: 他的儿子 - 高高的。

with a meaning (approximately) equal to:

2. > `Noun + (Adv of degree) + Adj`
   >
   > Ex: 他的儿子很高。
   >
   > Ex: *His son is tall.*

From the previous post, @username_2:

> There is no grammar difference between 你的脸很红 [structure 2.] and 你的脸红红的 [structure 1.]. 红红的 acts the same as 很红.

**I don't understand how 1. and 2. are *grammatically* equivalent**. I believe:

* 2. is a *complete sentence*: the Noun (他的儿子) is the subject, the (Adv of degree) + Adj (很高) is the predicate and the Adj (高), the adjectival verb.
* 1. is only a *noun phrase*, without Verb and Predicate. We can see it because the topic - comment structure makes it equivalent to:
  > `Adj + Adj + 的 + Noun`
  >
  > Ex: 他的高高的儿子。

**Where I am wrong in 1.? How can `Adj + Adj + 的` work as a predicate with a verb?**

---

A few **examples** of the **grammatical equivalence** of both structures:

> 这只小猫毛长长的，白白的，非常漂亮。
>
> The hair of this small cat is long, white and extremely pretty.

Here, 长长的 and 白白的 are grammatically equivalent to 非常漂亮.

> 这个孩子的眼睛大大的，和她的妈妈一样。
>
> This kid's eyes are big, just like his mother.

Here, 这个孩子的眼睛大大的 is translated to the complete sentence *This kid's eyes are big*.

After some reflection, I believe **the underlying grammar** of the *topic - comment* `Noun - Adj + 的` sentence is:

> `Noun - (是) + Adj + 的`
>
> Noun - (is) an Adj one.

**So the verb `是` is omitted, the predicate is `(是) + Adj + 的` and the subject is `Noun`.** This is because `Adj + 的` *nominalizes* the `Adj`, and we still need a verb. (If anyone can provide an alternative explanation, I would be interested to hear it).

In the example:

> 他的儿子 - 高的。
>
> His son - (is) a tall one.

---

There are two *alternative* ways to express it:

1. **Explicitly with 是**:

   > 他的儿子 是 高的。
   >
   > His son *is* a tall one.

   Although this introduces some emphasis on the adjective ([@username_2, @blackgreen](https://chinese.stackexchange.com/a/40001/25265)).
2. **`Noun + (Adv of degree) + Adj` structure**:

   > 他的儿子很高。
   >
   > His son is tall.

---

A *different grammatical* expression is the **noun phrase `Adj + 的 + Noun`** (@username_1, @username_2):

> 他的高的儿子。
>
> His tall son.

---

**A reduplication of adjectives `Adj + Adj` is still an `Adj`**, so all the previous grammatical considerations hold.

However, as pointed by [@username_2](https://chinese.stackexchange.com/a/40002/25265), a reduplication of the adjective has a different semantic meaning: the adjective becomes more *vivid, cutie, lively, etc.*

Really strange that as a Chinese I found this grammer never met before. Please forget your "nonce + adj + adj" form. This is just an eliptical sentence.

To make this simple, you should know a `basic sentence` structure:

`主语`(subject) + `谓语`(predicate) + `宾语` (object)

so:

* `他的儿子高高的`: `他的儿子`(主) + (省略了 `是` 这个谓语) + `高高的` (宾语)
* equivalent Chinese: His son `is` very tall.

and:

* `小猫白白的`: `小猫`(主) + (省略了 `是` 这个谓语) + `白白的` (宾语)
* equivalent English: The cat `is` white.

[Noun + Adj X2 + 的] = [Noun + degree adv + adj]

* Both are 'topic-comment' sentence
* [Adj X2 + 的] functions the same as [degree adv + adj] in this case (a noun at the beginning but no noun at the end)
