Because in Spanish
People keep asking Justin why, and today he finally has to answer.
You'll learn to give a reason with porque, name your main reason, and politely ask someone to explain theirs. There's also a softer way to ask if there's a reason at all.
By the end, you can answer any "why" question without a long speech.

Scene — a promise on Saturday
Saturday morning at Café Laurel. Alex just heard that Justin turned down the market trip, and he wants to know why.
Yako is on his two chairs, quietly guarding the tin under the table.

Learn — because and why
Six lines, one job: connecting actions to reasons.
Four of them answer a why question, and two ask one back. Notice how porque never changes, no matter who is talking.

Lo hice porque ___
I did it because ___
When to use it: Say this to explain a past action with its real reason.
Hice is the preterite of hacer, so this line is about something already done.
Say it: Porque sounds like POR-keh.

Es porque ___
It's because ___
When to use it: Say this when the reason follows directly, right after a why question.
A quick, light answer. You can add the full reason or leave it implied.

La razón principal es ___
The main reason is ___
When to use it: Say this when there are several reasons but one matters most.
Razón is feminine, so it takes la, and the adjective principal comes after.
Say it: Razón stresses the last syllable: rah-SOHN.

No pude porque ___
I couldn't because ___
When to use it: Say this to explain why you couldn't do something in the past.
Pude is the preterite of poder, so it's about a specific past moment.

¿Podrías explicar por qué ___?
Could you explain why ___?
When to use it: Say this to politely ask for a fuller explanation, not just one word.
Podrías is the conditional of poder, softer than puedes.
Say it: Por qué is two words when it asks a question.

¿Hay alguna razón por la que ___?
Is there a reason ___?
When to use it: Say this to ask gently whether a reason exists at all.
Por la que links the reason to the thing you're asking about.
Story — the reason, not the tin
Alex wants one clear reason, and Justin has one: a promise to Amanda.
Watch how each because line carries a different shade of the same answer. Yako has his own agenda at the end.
- Alex walks over to the table with the market list still in his hand.
- AlexJustin, dijiste que no al sábado. ¿Por qué?Justin, you said no to Saturday. Why?
JustinLo hice porque prometí ayudar a Amanda.I did it because I promised to help Amanda.- Alex¿Podrías explicar por qué no me avisaste antes?Could you explain why you didn't tell me earlier?
JustinDéjame pensar. Es porque se me cayó el internet.Let me think. It's because my internet dropped.- Alex¿En serio? Otra vez, Justin.Seriously? Again, Justin.
JustinSí. La razón principal es que Amanda tiene una entrevista.Yes. The main reason is that Amanda has an interview.- Alex¿Y no puedes cambiarla para el domingo?And you can't move it to Sunday?
JustinNo pude porque ella solo tiene ese día libre.I couldn't because she's only free that day.
Yako¿Hay alguna razón por la que yo no pueda ir con Alex?Is there a reason I can't go with Alex?- AlexClaro que puedes venir, Yako. Nos vemos el sábado.Of course you can come, Yako. See you Saturday.
- Yako climbs onto his two chairs, ready to give a long speech about the tin.
JustinSin discursos, Yako. La lata se queda.No speeches, Yako. The tin stays.
YakoBueno. Yo solo pasaba.Fine. I was just passing through.
