Questions & Answers about El lunes compré los billetes en una agencia de viajes.
Why does it say el lunes instead of using a word for "on"?
In Spanish, you don't use a preposition like "on" for days of the week. Instead, you just use the definite article el (the). So, el lunes literally means "the Monday," but it translates to "on Monday."
Why is compré in the preterite tense here?
Can I use billetes for any kind of ticket?
In Spain, billetes is specifically used for transportation tickets (like a train, bus, or plane ticket) and banknotes (paper money). If you were buying tickets for a cinema or a concert, you would use entradas. Note that in Latin America, you will often hear boletos or pasajes for travel instead.
Why is it agencia de viajes instead of putting the word for "travel" first?
In English, you can stack nouns to describe things, like "travel agency." Spanish doesn't do this. Instead, it uses the formula: [Main Thing] + de + [Descriptive Noun]. So, "travel agency" becomes agencia de viajes (literally "agency of travels"). Notice that viajes is plural here, which is standard for this phrase.
