A mi abuela le gustan los higos con queso.

Because the thing being liked is los higos (the figs), and that noun is plural.

With gustar, the verb agrees with the thing that is pleasing, not with the person who likes it.

• Me gusta el libro. = I like the book.
• Me gustan los libros. = I like the books.

So here:

• los higos = plural
• therefore gustan = plural

If it were singular, you would say:

• A mi abuela le gusta el higo con queso.

Yes, they both point to the same person, and that is normal Spanish.

This is a very common pattern with gustar and similar verbs:

• A mi abuela names the person clearly
• le is the required indirect object pronoun

So Spanish often says both:

• A mi abuela le gustan...
• literally: To my grandmother, ... are pleasing to her

The pronoun le is usually kept even when the full noun is present. It can help with:

• grammar
• clarity
• emphasis

This is not usually optional in standard Spanish.

Because mi abuela is the indirect object in this structure.

With gustar, the person who experiences the liking is introduced with a:

• A mí me gusta
• A Juan le gusta
• A mi abuela le gustan

So the a here is not exactly the same as the English word to, but it often works similarly in the literal structure:

• A mi abuela le gustan los higos con queso
• literally: To my grandmother, figs with cheese are pleasing

Because gustar does not work like the English verb to like.

In English:

• My grandmother = subject
• likes = verb
• figs = object

In Spanish with gustar:

• los higos = subject
• gustan = verb
• a mi abuela / le = indirect object

So the structure is closer to:

• Figs are pleasing to my grandmother

That is why learners often need to stop translating word-for-word from English.

Spanish often uses the definite article to talk about things in a general sense, especially with foods and things people like or dislike.

So:

• Me gustan los higos. = I like figs.
• Le gusta el café. = He/She likes coffee.

In English, we often leave the article out:

• I like figs
• She likes coffee

But in Spanish, using los here is very natural and usually preferred.

Because queso here is being used in a general way: with cheese as an accompaniment or ingredient, not with a specific cheese already identified.

So:

• los higos con queso = figs with cheese

If you said con el queso, it would usually sound like:

• with the cheese
• meaning some specific cheese already known from the context

Compare:

• Pan con queso = bread with cheese
• Pan con el queso que compraste ayer = bread with the cheese you bought yesterday

Most naturally, it describes los higos:

• los higos con queso = figs with cheese

So the whole thing means that your grandmother likes figs served with cheese, not necessarily figs on their own.

If you removed it:

• A mi abuela le gustan los higos.
• Your grandmother likes figs.

Adding con queso makes the liked item more specific.

Yes. Spanish word order is more flexible than English, especially with gustar.

The most neutral version is:

• A mi abuela le gustan los higos con queso.

But you could also say:

• Los higos con queso le gustan a mi abuela.
• Le gustan los higos con queso a mi abuela.

These are all grammatical, though they may sound different in emphasis.

What usually stays the same is:

• the pronoun le
• the plural verb gustan

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

For example, if you are already talking about your grandmother, you can say:

• Le gustan los higos con queso.

But by itself, le could mean:

• to him
• to her
• to you (formal)

So a mi abuela is useful when you want to make the meaning clear or add emphasis.

Because le is an indirect object pronoun, while la is a direct object pronoun.

With gustar, the person is treated as an indirect object:

• me
• te
• le
• nos
• os
• les

So:

• A mi abuela le gustan... = correct

Not:

• A mi abuela la gustan... = incorrect

Almost, but the verb would need to agree correctly:

• A mi abuela le encantan los higos con queso.

Like gustar, encantar also agrees with the thing that causes the feeling.

So:

• le gusta = she likes
• le encantan = she loves / she really loves

Because los higos is plural, you need encantan, not encanta.

No. The grammatical subject is los higos con queso.

A good test is verb agreement:

• gustan is plural
• it matches los higos
• it does not match mi abuela, which is singular

So:

• subject: los higos con queso
• indirect object: a mi abuela / le

This is one of the most important things to understand about gustar.

Yes, several common points:

1. Don’t translate word-for-word from English.
   Spanish is not saying my grandmother likes... in the same structure.

2. Make the verb agree with the thing liked.

   • gusta for singular
   • gustan for plural

3. Keep the indirect object pronoun.

   • A mi abuela le... not just A mi abuela gustan...

4. Use the article with general nouns when natural in Spanish.

   • los higos

5. Remember that the person is introduced with a.

   • A mi abuela

If you get those five things right, you are handling the sentence very well.
