A mi tía le encanta la alcachofa con rábano y pepinillo.

Yes, they both point to the same person, but they do different jobs in Spanish.

• le is the indirect object pronoun required with verbs like gustar and encantar
• a mi tía names the person more clearly and can also add emphasis

So the structure is very normal:

• A mi tía le encanta... = My aunt loves...

Spanish often uses this kind of double marking:

• A Juan le gusta el café
• A mis padres les encanta viajar

Even when the person is stated, the pronoun is usually still kept.

Because encantar here works like gustar.

In English, we say:

• My aunt loves artichoke

But in Spanish, the structure is closer to:

• Artichoke is very pleasing to my aunt

So the grammatical subject is la alcachofa, not mi tía.

That is why the verb agrees with la alcachofa:

• la alcachofa = singular
• therefore encanta = singular

Compare:

• A mi tía le encanta la alcachofa = She loves artichoke
• A mi tía le encantan las alcachofas = She loves artichokes

Because after verbs like gustar/encantar, the person affected is introduced with a.

So:

• A mi tía le encanta...
• A mí me gusta...
• A ellos les gustan...

This a is not the same as the English preposition to in a simple word-for-word way, but it often corresponds to that idea.

Without a, the sentence would be ungrammatical in this structure.

Spanish often uses the definite article with foods, especially when speaking about them generally or as things someone likes.

So:

• Me gusta el café
• Le encanta la pizza
• Nos gustan las fresas

Here la alcachofa can mean artichoke in a general sense, or a specific artichoke dish depending on context.

English often drops the article where Spanish keeps it.

Because the true subject is still only la alcachofa.

The part con rábano y pepinillo is just a phrase describing the artichoke:

• the artichoke with radish and gherkin

So the subject is singular, and the verb stays singular:

• le encanta

If the foods were listed as separate things your aunt loves, then the verb would be plural:

• A mi tía le encantan la alcachofa, el rábano y el pepinillo

There, the subject is a plural list, so encantan is needed.

Because after con, Spanish often leaves out the article when mentioning ingredients or accompaniment in a general way.

So:

• la alcachofa con rábano y pepinillo
• pan con queso
• ensalada con tomate

This sounds natural when talking about what something contains or is served with.

You could add articles in some contexts, but that usually sounds more specific:

• con el rábano y el pepinillo = with the radish and the gherkin/pickle

That would suggest particular, identifiable items.

It modifies la alcachofa.

So the structure is:

• A mi tía = to my aunt
• le encanta = is loved by her / she loves
• la alcachofa con rábano y pepinillo = the artichoke with radish and gherkin

In other words, your aunt loves the artichoke served with radish and gherkin, not necessarily three separate favourite foods.

In Spain Spanish:

• pepino = cucumber
• pepinillo = gherkin / pickled cucumber / pickle

So pepinillo is not just a random smaller version of pepino in meaning. In everyday use, it usually refers to the pickled kind.

That is why pepinillo is the better choice if the meaning shown to the learner is something like pickle or gherkin.

The accent marks show stress.

• tía is stressed on tí
• rábano is stressed on rá

They also help with pronunciation and, in some cases, prevent the word from being read with the wrong syllable stress.

For tía, the accent also helps show that í-a is pronounced in separate syllables:

• tí-a

not as one blended syllable.

A simple guide:

• A mi tía ≈ ah mee TEE-ah
• le encanta ≈ leh en-KAN-tah
• la alcachofa ≈ lah al-kah-CHO-fah
• con rábano ≈ kon RAH-bah-no
• y pepinillo ≈ ee peh-pee-NEE-yo

A few useful pronunciation notes for Spain:

• c before a in alcachofa sounds like a normal k
• ch is like English ch
• ll in pepinillo is often pronounced like a y sound in many parts of Spain
• y before a word is pronounced like ee

Yes, it is grammatical, but it does not sound the same.

• A mi tía le encanta... is very natural and idiomatic
• Mi tía ama... is structurally simpler for an English speaker, but amar can sound stronger, more emotional, or less natural with foods in many contexts

For preferences and things people really like, Spanish very often prefers:

• gustar
• encantar

So A mi tía le encanta... is the more natural choice here.

Yes. Spanish word order is flexible.

These are all possible, depending on emphasis:

• A mi tía le encanta la alcachofa con rábano y pepinillo
• La alcachofa con rábano y pepinillo le encanta a mi tía
• Le encanta la alcachofa con rábano y pepinillo a mi tía

The most neutral and learner-friendly version is the original one.

Spanish often moves parts of the sentence around for emphasis, but the pronoun le usually stays with the verb.

The indirect object pronoun would change:

• A mis tías les encanta la alcachofa con rábano y pepinillo

Here:

• a mis tías = to my aunts
• les = to them

But encanta stays singular because the thing loved, la alcachofa, is still singular.

If both the person and the thing were plural:

• A mis tías les encantan las alcachofas

So remember:

• person liked-by = affects me/le/nos/les
• thing liked = controls gusta/gustan, encanta/encantan
