Me gusta hojear revistas en la sala de espera.

Because gustar works differently from to like in English.

In Spanish, gustar literally works more like to be pleasing to. So:

• Me gusta hojear revistas = Flipping through magazines is pleasing to me
• me = to me
• gusta = is pleasing

So yo gusto would not mean I like. It would usually mean something more like I am pleasing / I am liked, depending on context.

Because the thing that gusta here is not revistas by itself. The subject is the whole action:

hojear revistas = to flip through magazines

An infinitive phrase like hojear revistas is treated as singular, so Spanish uses gusta.

Compare:

• Me gusta hojear revistas. = I like flipping through magazines.
• Me gustan las revistas. = I like magazines.

In the second sentence, las revistas is the subject, and it is plural, so you use gustan.

Me is an indirect object pronoun meaning to me.

In sentences with gustar, the structure is usually:

• Me gusta... = It is pleasing to me...
• Te gusta... = It is pleasing to you...
• Le gusta... = It is pleasing to him/her/you (formal)...

So in this sentence, me tells you who likes the action: I do.

Hojear means to leaf through, to flip through, or to browse pages without necessarily reading everything carefully.

So:

• hojear revistas = flip through magazines
• leer revistas = read magazines

If the idea is sitting in a waiting room and casually looking through magazines, hojear is a very natural choice.

Yes. Hoja means leaf or sheet/page, and hojear comes from that idea. It suggests moving through the pages of a book or magazine.

So it is a very visual verb: you are turning the pages rather than reading deeply.

Because Spanish often leaves out the article when talking about things in a general, non-specific way.

So:

• hojear revistas = to flip through magazines in general
• hojear las revistas = to flip through the magazines (specific ones)

In your sentence, it sounds general, not like there are particular magazines already identified.

It is a prepositional phrase showing location:

• en = in
• la sala de espera = the waiting room

So en la sala de espera tells you where the action happens.

It modifies the action hojear revistas: to flip through magazines in the waiting room

Sala de espera is the normal fixed expression for waiting room.

Spanish often uses noun + de + noun for this kind of phrase:

• sala de espera = waiting room
• literally: room of waiting

It is idiomatic and standard. Sala para esperar would sound unusual here.

Yes. Spanish word order is flexible, especially with phrases like en la sala de espera.

For example, all of these are possible:

• Me gusta hojear revistas en la sala de espera.
• En la sala de espera me gusta hojear revistas.
• Me gusta, en la sala de espera, hojear revistas. (more marked)

The original version is the most neutral and natural.

In standard Spanish pronunciation:

• the h is silent
• the j is a strong throat sound, like the j in jamón
• it sounds roughly like o-heh-AR or o-kheh-AR, depending on how you hear the Spanish j

A rough guide:

• hojear → o-heh-AR

Also, the stress falls on the last syllable: ho-je-AR.

Yes, in many contexts ojear is also used to mean to glance through or to browse. In everyday usage, ojear and hojear are often treated as very similar.

That said, hojear is especially associated with turning pages, so it fits very well with revistas.

Because in Spanish, after gustar you can like an action, and actions are often expressed with the infinitive.

So:

• Me gusta leer. = I like reading / I like to read.
• Me gusta viajar. = I like travelling / I like to travel.
• Me gusta hojear revistas. = I like flipping through magazines.

The infinitive acts like a noun here: the action of flipping through magazines.

Yes, slightly.

• en la sala de espera = in the waiting room
• en una sala de espera = in a waiting room

With la, it can sound like a specific waiting room or simply the usual, familiar place type in context. With una, it is more indefinite: any waiting room.

Both are grammatical, but they are not exactly the same nuance.

Not naturally. This sentence specifically means that you like the action of flipping through magazines in the waiting room.

If you wanted to say I like the magazines in the waiting room, you would say:

• Me gustan las revistas de la sala de espera.

That changes the subject to las revistas, so the verb becomes plural: gustan.
