I got stuck with this sentence 'This is also a period of enormous physical change and adolescents experience changes in their physical development at a rate unparalleled since infancy.'. I am confused about why the adjective 'unparalleled' is put behind the noun'rate'. Are there any special functions or meanings? And can anybody tell me how to analyse this structure grammatically? Thanks a lot.

If you wanted to put the adjective before the noun, it would have to be the whole adjective. It might look a bit "forced", but native speakers certainly wouldn't argue with the syntactic validity of ...at an unparalleled-since-infancy rate (the hyphens are just an orthographic courtesy to help the reader parse the utterance correctly).– FumbleFingersCommented Jan 11, 2023 at 12:52

The whole phrase unparalleled since infancy describes rate. (Their bodies change at a faster rate than they have experienced since they were babies.)
The sentence wouldn't make sense if the phrase was split up in order to put the adjective before the noun.
This sentence is an example of whiz-deletion, where a relative pronoun and be-verb are omitted from a relative clause. Here is the sentence with the relative pronoun and be-verb present:
This is also a period of enormous physical change and adolescents experience changes in their physical development at a rate which is unparalleled since infancy.

1Thank you so much! I think I made a mistake. I separated the word 'unparalleled' and the phrase 'since infancy' , so it led to my misunderstanding.– kungnoCommented Jan 21, 2023 at 19:38
