A mi hermano le encanta la paella con verduras.

Yes, they both point to the same person, but this is very normal in Spanish.

This is called clitic doubling:

• a mi hermano = the full phrase, used for clarity or emphasis
• le = the indirect object pronoun that usually goes with verbs like gustar and encantar

So Spanish often says both:

• A mi hermano le encanta la paella con verduras.

This is not considered redundant in the way it would be in English. In fact, with this kind of structure, using le is basically expected.

The a introduces the person who is affected by the verb — in this case, the person who loves the paella.

With verbs like gustar and encantar, Spanish does not structure the sentence like English My brother loves paella. Instead, it works more like:

• Paella is pleasing/delightful to my brother
• or more literally with encantar: Paella enchants my brother

So a mi hermano marks to my brother.

Because the verb agrees with la paella, which is singular.

In this kind of sentence, the thing being liked is the grammatical subject:

• la paella = singular → encanta
• las verduras = plural → encantan

Compare:

• A mi hermano le encanta la paella.
• A mi hermano le encantan las verduras.

So the verb does not agree with mi hermano. It agrees with the thing that causes the feeling.

No. The grammatical subject is la paella con verduras.

That can feel strange to English speakers, because English says:

• My brother loves paella

But Spanish structures it differently:

• A mi hermano le encanta la paella con verduras
• literally: To my brother, the paella with vegetables is delightful / enchants him

So:

• mi hermano = indirect object / experiencer
• la paella con verduras = subject
• encanta agrees with la paella

Encantar is stronger than gustar.

Roughly:

• gustar = to like
• encantar = to love / to really love / to adore

So:

• A mi hermano le gusta la paella con verduras = My brother likes vegetable paella
• A mi hermano le encanta la paella con verduras = My brother loves vegetable paella / really loves paella with vegetables

It works grammatically like gustar, but expresses a stronger feeling.

Spanish often uses the definite article with general nouns, especially when talking about foods, activities, or things someone likes.

So Spanish commonly says:

• Me gusta el café
• Le encanta la música
• Nos gusta la paella

In English, we often leave the article out:

• I like coffee
• He loves music
• My brother loves paella

But in Spanish, using la here is very natural.

Yes, if the context already makes it clear who le refers to.

You could say:

• Le encanta la paella con verduras.

That means:

• He/She loves paella with vegetables.

But without a mi hermano, le could mean to him, to her, or even to you in some formal contexts, depending on the situation. So adding a mi hermano makes it clear and can also add emphasis.

Because with encantar in this kind of construction, the person is treated as an indirect object, not a direct object.

So Spanish uses:

• me
• te
• le
• nos
• os
• les

Examples:

• Me encanta
• Te encanta
• Le encanta

Not:

• lo encanta

That is because the structure is like it is delightful to him, not it enchants him in the ordinary direct-object sense English might suggest.

Con verduras means with vegetables.

So:

• la paella con verduras = paella with vegetables

If you say paella de verduras, that usually means vegetable paella as a type or category of paella.

The difference is subtle:

• con verduras focuses on what it comes with or contains
• de verduras can sound more like the dish is specifically a vegetable version

Both can be possible in real life, but con verduras is perfectly natural and means exactly with vegetables.

Yes. Spanish word order is more flexible than English word order.

The sentence could also be:

• La paella con verduras le encanta a mi hermano.

This still means the same thing, but the emphasis changes a little. The original sentence:

• A mi hermano le encanta la paella con verduras is a very natural, neutral way to say it.

Putting a mi hermano first can highlight who loves it.

No, not with this meaning.

Encantar does not work like a normal transitive verb here. You cannot use it like:

• Mi hermano encanta la paella

That would mean something more like My brother enchants the paella, which makes no sense.

To express my brother loves paella, Spanish uses the gustar/encantar structure:

• A mi hermano le encanta la paella con verduras.

So this is one of those verbs where you need to learn the special pattern.

Here, mi hermano simply means my brother.

Spanish normally uses the possessive adjective directly before the noun:

• mi hermano = my brother
• mi hermana = my sister

You could also say un hermano mío in other contexts, but that usually has a slightly different feel, more like a brother of mine.

In this sentence, mi hermano is the normal and natural choice.

You would change both the pronoun phrase and possibly the verb agreement depending on the thing loved.

For my brothers love paella with vegetables:

• A mis hermanos les encanta la paella con verduras.

Changes:

• mi hermano → mis hermanos
• le → les
• encanta stays singular because la paella is singular

If the thing loved were plural, then the verb would also change:

• A mis hermanos les encantan las verduras.

So remember:

• the pronoun changes with the person
• the verb changes with the thing being liked
