What is the part of speech in each sentence? Is my explanation right?

1. This book is for you.
['For you' is an adverb phrase.]

2. The gift for you is a book.
['For you' is an "adjective" phrase.]

3. I bought this book for you.
['For you' is an adverb phrase.]

4. This book for you is very good.
['For you' is an "adjective" phrase.]

You are referring to each prepositional phrase's usage, not the part of speech.

Sentence 1 --
This = pronoun
book = noun
is = verb
for = preposition
you = pronoun

A prepositional phrase is comprised of a preposition plus its object (which can be either a noun or a pronoun). There is often an article and/or adjective between the preposition and its object.

Please revise your original statement. You're not referring to parts of speech here, but to the use of prepositional phrases: adjectival or adverbial.
======================================
Thank you for your help. I will post again.
"For you" is a prepositional phrase. It can be an adverbial phrase and an adjective phrase. Is my explanation correct? Especially, what about #1?

1. This book is for you.
['For you' is an adverb phrase.]

2. The gift for you is a book.
['For you' is an "adjective" phrase.]

3. I bought this book for you.
['For you' is an adverb phrase.]

4. This book for you is very good.
['For you' is an "adjective" phrase.]

I would change one word in your explanation:

"For you" is a prepositional phrase. It can be an adverbial phrase or an adjective phrase.

And yes, I agree with your explanations of #s 1-4.

In order to determine whether "for you" is an adverb phrase or an adjective phrase in each sentence, we need to analyze its function and how it modifies the rest of the sentence.

Let's break down each sentence:

1. This book is for you.
- "For you" is indicating the recipient of the action "is" (the verb). It is modifying the verb "is" and answering the question "for whom?" Therefore, "for you" is functioning as an adverbial phrase, specifically an adverbial prepositional phrase. It tells us the purpose or intended audience of the book.

2. The gift for you is a book.
- In this sentence, "for you" is describing the noun "gift" by answering the question "for whom?". It is modifying the noun "gift" and identifying its recipient. Therefore, "for you" is functioning as an adjectival phrase, more specifically an adjectival prepositional phrase.

3. I bought this book for you.
- Again, "for you" is indicating the recipient of the action "bought" (the verb). It is modifying the verb "bought" and answering the question "for whom?". Thus, "for you" is functioning as an adverbial phrase, specifically an adverbial prepositional phrase.

4. This book for you is very good.
- In this sentence, "for you" is describing the noun "book" by answering the question "for whom?". It is modifying the noun "book" and identifying its intended audience. Therefore, "for you" is functioning as an adjectival phrase, more specifically an adjectival prepositional phrase.

Therefore, your explanation is correct for sentences 2 and 4, where "for you" is indeed functioning as an adjective phrase. However, in sentences 1 and 3, "for you" is functioning as an adverbial phrase, not an adjective phrase.
