Si quieres, podemos tutearnos; el trato informal me resulta más natural.

Tutearnos comes from tutearse, which means to address each other using tú instead of usted.

In this sentence, it means something like:

• we can use tú with each other
• we can be on tú terms

This is specifically about the form of address, not just about being friendly in a general sense.

The -nos means ourselves / each other here.

So:

• tutear = to address someone as tú
• tutearnos = to address each other as tú

It is a reciprocal idea: both speakers would use tú with one another.

Also, after a conjugated verb like podemos, Spanish often allows the pronoun to attach to the infinitive:

• podemos tutearnos
• nos podemos tutear

Both are correct.

Podemos tutearnos sounds softer and more polite than a direct instruction.

It suggests:

• we can use tú, if you like
• it would be fine for us to speak informally

This is common when proposing a change in register without sounding pushy.

A more direct version might feel stronger or less tactful.

Si quieres literally means if you want.

In this sentence, it acts as a polite softener. It gives the other person the choice and avoids sounding imposing.

It is very common in Spanish to begin a suggestion this way:

• Si quieres, ...
• If you want, ...

Grammatically, this is a normal real condition with the present tense:

• si quieres = if you want
• podemos tutearnos = we can use tú with each other

Its core meaning is specifically about using tú instead of usted.

In Spain, this is very natural because the tú / usted distinction is a central part of everyday speech.

So tutearse is not just to speak informally in a vague way. It specifically means to use the familiar second-person form.

El trato informal means informal address or an informal way of interacting with someone.

Here, trato does not mean a business deal. It means something more like:

• the way people address each other
• the social tone of the interaction
• the level of formality used

So el trato informal refers to using a less formal register, such as tú rather than usted.

Both ideas are possible, but me resulta más natural is especially idiomatic.

Resultar often means something like:

• to seem
• to feel
• to come across as

So me resulta más natural means:

• it feels more natural to me
• it comes more naturally to me

Compared with es más natural para mí, this wording sounds a bit more personal and nuanced. It presents the idea as the speaker’s impression or experience, rather than as a flat statement.

The comparison is implied.

It means:

• more natural than using formal address
• more natural than speaking with usted

Spanish often leaves this second part unstated when it is obvious from context.

So even though the sentence does not explicitly say que el trato formal, that idea is understood.

Me is an indirect object pronoun meaning to me.

So:

• me resulta = it feels / seems to me

This structure is very common in Spanish when describing how something appears to someone:

• me parece bien = it seems fine to me
• me resulta extraño = it seems strange to me
• me resulta más natural = it feels more natural to me

Yes. Both are correct:

• podemos tutearnos
• nos podemos tutear

With a conjugated verb plus an infinitive, the object/reflexive pronoun can usually go:

• before the conjugated verb, or
• attached to the infinitive

In this sentence, podemos tutearnos is very natural and elegant.

The semicolon links two closely related complete clauses:

• Si quieres, podemos tutearnos
• el trato informal me resulta más natural

It works a bit like a stronger comma or a lighter full stop.

It shows that the second clause explains or justifies the first one: the speaker suggests using tú because informal address feels more natural to them.

In less formal writing, some people might use a comma or a full stop instead, but the semicolon is perfectly good here.

Yes, it fits Spain Spanish very well.

In Spain, the contrast between tú and usted is very active in everyday life, and moving from usted to tú is a common social step. Saying podemos tutearnos is a natural way to propose that shift.

In many parts of Latin America, the sentence is still understandable, but local habits may differ:

• usted may be used more or less often depending on the country
• some regions use vos
• the exact social feel of switching forms can vary

So for a learner of Spanish from Spain, this sentence is especially useful.

Yes. Some common alternatives are:

• Si quieres, nos tuteamos.
• Si quieres, podemos hablarnos de tú.
• Si quieres, podemos tratarnos de tú.

These are all related, but they are not identical in tone:

• tutearnos / nos tuteamos is compact and very direct about using tú
• tratarnos de tú is also very common and clear
• hablarnos de tú is understandable, but a bit less fixed as an expression than tratarse de tú or tutearse

In Spain, tutearnos and tratarnos de tú are especially natural choices.
