Mi padre enciende la parrilla en la terraza cuando vienen mis tíos a comer.

In Spanish, the normal way to say my father before a noun is mi padre.

• mi = my
• padre = father

You do not usually say el mi padre in modern standard Spanish.

Padre mío does exist, but it is not the normal neutral way to say my father. It sounds much more expressive, literary, old-fashioned, or emotional depending on context. In everyday speech, mi padre is the standard form.

Enciende is the third-person singular present of encender.

Here it means something like:

• switches on
• lights
• starts

With la parrilla, the exact translation depends on what kind of grill is meant:

• If it is electric or gas, turns on works well.
• If it uses charcoal or fire, lights may be more natural.

So Mi padre enciende la parrilla means My father lights/turns on the grill.

Spanish often uses the present tense to describe habitual actions or routines, just like English does.

So this sentence means something like:

• My father lights the grill on the terrace when my uncles come over to eat.

This is not necessarily happening right now. It describes what usually happens on those occasions.

So:

• enciende = he lights / he turns on
• vienen = they come

Both are in the present because the sentence describes a repeated pattern.

Both are possible, but cuando vienen mis tíos is very natural in Spanish.

Spanish word order is often more flexible than English. The subject can appear after the verb, especially when:

• introducing who is doing the action
• focusing on the event first
• in subordinate clauses like this one

So:

• cuando vienen mis tíos = very natural
• cuando mis tíos vienen = also grammatical

The version with the subject after the verb can sound a bit smoother or more natural in many contexts.

Spanish usually leaves out subject pronouns when the verb ending already shows who the subject is.

For example:

• enciende already tells you it is he/she/it
• vienen already tells you it is they

Since the sentence already has:

• Mi padre
• mis tíos

there is no need to add él or ellos.

In fact, adding them would often sound unnecessary unless you want contrast or emphasis.

Spanish uses the definite article el / la / los / las very often, including in places where English may or may not use the.

Here:

• la parrilla = the grill
• la terraza = the terrace / patio

These are specific, identifiable things in the situation, so the article is natural.

The sentence is not talking about just any grill or any terrace, but the one at the house or in that setting.

En la terraza literally means on the terrace or on the patio/terrace area.

In Spanish from Spain, terraza can refer to an outdoor space attached to a house or apartment, such as:

• a terrace
• a patio-like outdoor area
• sometimes a balcony-like space, depending on context

So the best English translation depends on the real-life setting. The Spanish word itself is completely normal here.

A comer is very common after verbs of movement like venir, ir, salir, etc.

Here, venir a + infinitive expresses purpose:

• vienen a comer = they come to eat
• more naturally in English: they come over for a meal / they come to eat

So the a does not mean to in the sense of direction here. It introduces the reason or purpose of coming.

Other examples:

• Voy a estudiar. = I’m going to study.
• Salimos a cenar. = We go out to have dinner.

Sometimes para + infinitive can express purpose, but after verbs of movement, a + infinitive is often the most natural choice.

So:

• vienen a comer = very natural
• vienen para comer = possible in some contexts, but it can sound less neutral here

With venir, ir, salir, subir, bajar, and similar verbs, a + infinitive is a very common pattern.

So for a learner, venir a comer is the structure to remember.

This is a very common question.

Both forms can be correct, but they mean slightly different things.

In this sentence, cuando vienen is used because the speaker is talking about a habitual, repeated situation:

• when my uncles come over to eat
• meaning whenever they come

If you said cuando vengan, that would usually point more to a future event or a specific upcoming occasion:

• Mi padre encenderá la parrilla cuando vengan mis tíos a comer.
• My father will light the grill when my uncles come over to eat.

So:

• cuando + present indicative = repeated/habitual event
• cuando + present subjunctive = future event not yet realized

It is understandable and grammatical, but vocabulary can vary.

In Spain, depending on the region and context, people might also say:

• barbacoa for a barbecue or barbecue grill
• parrilla for a grill or grate

So enciende la parrilla is fine, but in some everyday situations a Spaniard might more naturally say something involving barbacoa, especially if they mean an outdoor barbecue setup.

Still, the sentence as written is perfectly valid Spanish.

Grammatically, mis tíos is the masculine plural form.

That can mean:

• my uncles (all male), or
• my aunt and uncle / my aunts and uncles, if the group is mixed

Spanish uses the masculine plural for mixed groups.

So without more context, mis tíos could mean:

• several uncles, or
• a mixed group of relatives including at least one male

But many textbook translations will simply give my uncles.

Yes, very often that is the most natural English translation.

Spanish venir just means to come, but in English, when relatives are visiting someone’s home for a meal, come over often sounds more natural.

So:

• vienen mis tíos a comer
  can naturally become
• my uncles come over to eat
• or my uncles come over for lunch / for a meal, depending on context

That is a translation choice, not a different grammar point in Spanish.

Yes, the Spanish present tense can sometimes refer to the future, especially in context. But in this sentence, the most natural reading is habitual.

Without extra context, learners should understand it as:

• My father lights the grill on the terrace when my uncles come over to eat.

If the speaker wanted a clearly future meaning for one occasion, Spanish would often use something like:

• Mi padre encenderá la parrilla en la terraza cuando vengan mis tíos a comer.

So the sentence as given is best understood as a routine or repeated event.
