Si te viene mejor, podemos vernos el miércoles después de clase.

Because si without an accent means if.

• si = if
• sí = yes

So in Si te viene mejor..., si introduces a condition: If it suits you better...

Literally, te viene mejor is something like it comes to you better, but that is not how it is understood in English.

In real use, venir bien / venir mejor means:

• to suit someone
• to be more convenient for someone
• to work better for someone

So:

• te viene bien = it suits you / it works well for you
• te viene mejor = it suits you better / it works better for you

The te means to you / for you.

This is a very common Spanish way to talk about convenience:

• ¿Te viene bien mañana? = Does tomorrow work for you?
• Me viene mejor por la tarde. = The afternoon works better for me.

Because the thing that suits you is understood as a singular idea, such as:

• this plan
• this option
• this time
• meeting on Wednesday after class

Spanish often leaves that subject unstated because it is obvious from context.

So te viene mejor really means something like:

• that works better for you
• that suits you better

Even though no explicit subject is written, the verb stays in third person singular: viene.

Because this is a real or possible condition, not a hypothetical or contrary-to-fact one.

Spanish commonly uses:

• si + present, then a present/future-like result

Here:

• Si te viene mejor, podemos vernos...
• If it works better for you, we can meet...

This is normal and natural.

Compare:

• Si tienes tiempo, hablamos. = If you have time, we’ll talk.
• Si quieres, vamos mañana. = If you want, we can go tomorrow.

You do not use the subjunctive after si in this kind of sentence.

Vernos comes from vernos, literally to see each other / to see ourselves, but in this context it means to meet.

So:

• podemos vernos = we can meet

After a conjugated modal verb like poder, Spanish often allows two positions for the pronoun:

• podemos vernos
• nos podemos ver

Both are correct.

In Spain, vernos is a very natural way to say meet up.

Because Spanish often uses reflexive/reciprocal forms to express the idea of meeting each other.

With nos, the idea is reciprocal:

• we see each other
• therefore, in context, we meet

Examples:

• Podemos vernos mañana. = We can meet tomorrow.
• Nos vemos luego. = See you later. / literally We’ll see each other later.

So this is not about looking at yourselves in a mirror. It is a standard way to talk about people seeing each other socially.

Yes. Both are correct.

• podemos vernos
• nos podemos ver

With a conjugated verb + infinitive, object/reflexive pronouns can usually go:

1. before the conjugated verb
2. attached to the infinitive

So both versions are grammatical. The meaning is the same.

In Spanish, days of the week often take the definite article.

So:

• el miércoles = on Wednesday
• el lunes = on Monday

The article is normal Spanish usage.

A few notes:

• Nos vemos el miércoles. = We’ll see each other on Wednesday.
• If you mean a repeated action, the article is also used:
  • Los miércoles tengo clase. = I have class on Wednesdays.

So the el here does not mean the Wednesday in a strange way; it is just how Spanish normally expresses days.

Because clase here is being used in a general, routine sense: after class.

Spanish often omits the article in expressions like this when referring to the activity or institutional setting in a general way.

So:

• después de clase = after class
• antes de clase = before class

But if you mean a specific class, you can use the article:

• después de la clase de historia = after the history class
• después de la clase que tuvimos ayer = after the class we had yesterday

In your sentence, después de clase sounds natural because it refers generally to when class is over.

Because the sentence starts with a conditional clause.

• Si te viene mejor = conditional clause
• podemos vernos el miércoles después de clase = main clause

In Spanish, it is standard to put a comma when the si clause comes first.

So:

• Si te viene mejor, podemos vernos...

If the main clause comes first, the comma is often omitted:

• Podemos vernos el miércoles después de clase si te viene mejor.

Both word orders are fine.

Very often, yes.

For convenience or scheduling, Spanish speakers very commonly use:

• venir bien
• venir mejor

These sound natural when discussing times, plans, and arrangements.

Examples:

• ¿Te viene bien a las cinco? = Does 5:00 work for you?
• Me viene mejor el jueves. = Thursday works better for me.

You can say things like es mejor para ti, but that often sounds more general or more explicitly evaluative, not as idiomatic for scheduling.

So in this sentence, Si te viene mejor... is a very natural choice.

Yes, often.

In Spain especially, quedar is very common for arranging to meet:

• Si te viene mejor, podemos quedar el miércoles después de clase.

That means essentially the same thing: If it suits you better, we can meet on Wednesday after class.

The nuance is slight:

• quedar focuses a bit more on arranging the meeting
• vernos focuses a bit more on seeing each other / meeting up

In many everyday situations, both are perfectly natural.

It is informal, because it uses te.

• te viene mejor = informal you
• formal would be le viene mejor

A more formal version could be:

• Si le viene mejor, podemos vernos el miércoles después de clase.

So the original sentence is appropriate for speaking to a friend, classmate, or someone you address with tú.

Normally, no.

In Spanish, days of the week are not capitalized unless they begin a sentence.

So:

• el miércoles ✔
• el Miércoles ✘

This is different from English, where Wednesday is always capitalized.

It breaks down like this:

• Si = if
• te viene mejor = it works better for you
• podemos = we can
• vernos = meet / see each other
• el miércoles = on Wednesday
• después de clase = after class

So the structure is:

[Condition] + [Main clause]

• Si te viene mejor,
  condition
• podemos vernos el miércoles después de clase.
  result / proposal

This is a very common and useful pattern in Spanish for making polite suggestions.
