This question is motivated from Why 的 in reduplication of adjectives "Noun + Adj + Adj + 的"?. In the answers, it was argued that the reduplication of adjectives structure:
Noun + Adj + Adj + 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:
Noun + (Adv of degree) + Adj
Ex: His son is tall.
From the previous post, @dan:
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:
- 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.
- 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
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:
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.
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.
