Is the syntax n+adj correct?

This is a question I answered a long time ago. At that time, I only analyzed it from a grammatical perspective. Now revise the answer:

Didn’t the person who asked the question say, “I saw apple red somewhere and it’s just such a short sentence.” So I looked up apple red and maybe I know the origin of apple red. I found an English children's song, song title: apple round apple red

Lyrics: apple round apple red

apple juicy apple sweet

apple apple I love you

apple sweet I love to eat

If this is the source, the answer should actually be apple red is an omission of Apple is red. Just like Chinese songs, there are many in Chinese songs Such an omission.

Attributive adjective position:

1. Generally, adjectives are placed before the noun they modify, which is what you call adj+n

2. There are some Adjectives can also be postpositioned as attributives

1 When modifying compound indefinite pronouns such as something anybody, they can be postpositioned

something red

2 Adjectives and other words form phrases as attributives postposition

a language easy to learn

3 Some adjectives that usually only serve as predicatives, such as alive aione asleep worthy unable, etc., sometimes also serve as attributives, but must be postpositioned

a girl worthy of confidence A girl worthy of trust

3 deep young and other words are placed after the noun in the expression of measurement

two meters deep

4 The participle phrase is postpositioned when used as an attributive

the girl standing by the window

Three. Some adjectives can be used as attributives before or after the noun

a nearby house = a house nearby

IV. Some adjectives have different prepositions and postpositions in meaning

the present situation the current situation

the student present

And the apple red you mentioned is also possible It’s a question of complements: the complement of red for apple is placed at the end
