Mi tutora revisa si la conjunción, la preposición y el adverbio quedan bien en el texto.

Mi without an accent is the possessive adjective meaning my.
Mí with an accent is a pronoun meaning me, used after a preposition, as in para mí.

So here mi tutora means my tutor / my female supervisor. The word tutora is feminine because the person being referred to is a woman. If it were a man, you would say mi tutor.

Revisa is the third-person singular present indicative form of revisar.

So it matches mi tutora:

• mi tutora revisa = my tutor checks / reviews

  In Spanish, the present tense can often mean either:

• a habitual action: my tutor checks
• or a current action, depending on context: my tutor is checking

Not exactly. This is a common false friend.

In Spanish, revisar often means:

• to check
• to look over
• to review
• to inspect

So in this sentence, revisa is more like checks or reviews, not necessarily rewrites.

If you mean revise in the sense of study again, Spanish often uses repasar. If you mean revise a text by changing it, revisar can still work, but its meaning is broader than English revise.

Here si means whether or if in the sense of an indirect yes/no question:

• revisa si... = checks whether...

So the idea is not a condition like if this happens, then.... It means she is checking whether those words fit well.

Also, this si has no accent. That matters because:

• si = if / whether
• sí = yes or himself/herself/itself after a preposition in some contexts

Because each noun has its own gender and Spanish normally uses an article with each one here.

• la conjunción = feminine
• la preposición = feminine
• el adverbio = masculine

Since the last noun is masculine, you cannot use one single article for the whole list. Repeating the articles makes the structure clear and natural.

English often omits articles in lists more freely, but Spanish usually sounds better here with each noun introduced separately.

Because together they form a compound subject. Even though each noun is singular, the whole group is plural:

• la conjunción, la preposición y el adverbio = three items together

So the verb must also be plural:

• quedan bien

If there were only one item, you would use singular:

• La conjunción queda bien en el texto.

Because bien is an adverb, and it modifies the verb quedan.

• bien = well
• bueno / buena = good

Here the sentence is talking about how those elements fit in the text, not describing them as good nouns.

So:

• quedan bien = they fit/work well
• not quedan buenos/buenas

Here quedar bien means something like:

• to fit well
• to sound right
• to work well
• to look right in context

It does not literally mean to stay here, even though quedar often has meanings related to remaining or staying.

In a sentence about writing, quedar bien en el texto means that the words or structures sound natural and appropriate in that text.

Because after revisar si, Spanish normally uses the indicative, not the subjunctive.

This si introduces an indirect question:

• Mi tutora revisa si quedan bien... = My tutor checks whether they fit well...

That is the normal pattern, just like:

• No sé si viene. = I don’t know whether he is coming.

The subjunctive would not normally be used here. So si queden bien would sound wrong in standard Spanish.

Because en shows that these language elements are being evaluated within the text.

• en el texto = in the text / within the text

The idea is that the tutor is checking whether the conjunction, preposition and adverb work properly in that written context.

A different preposition would change the meaning:

• del texto = of/from the text
• para el texto = for the text

So en el texto is the natural choice here.

Yes. In Spanish, items in a list are separated by commas, and normally there is no comma before the final y.

So this is standard:

• la conjunción, la preposición y el adverbio

That is different from English, where some writers use the Oxford comma before and. In standard Spanish, that final comma is usually not used in a simple list.

Because of Spanish stress rules.

Conjunción and preposición are stressed on the last syllable:

• con-jun-ción
• pre-po-si-ción

Words ending in n, s, or a vowel are normally stressed on the second-to-last syllable, so these words need a written accent to show that the stress is on the last one.

Adverbio is stressed naturally on the second-to-last syllable:

• ad-ver-bio

Since that follows the normal rule for a word ending in a vowel, no written accent is needed.
