Questions & Answers about ¿En serio vas a viajar?
Why do we say en serio instead of seriamente for 'seriously'?
Could I use the future tense viajarás instead of vas a viajar here?
Yes, ¿En serio viajarás? is grammatically correct. However, in spoken Latin American Spanish, using ir a plus an infinitive (like vas a viajar) is much more common for expressing future plans or intentions than the single-word future tense.
Why isn't the subject pronoun tú included in this sentence?
Do we always need the word a after vas?
Yes! When using the verb ir (to go) to talk about doing something in the future, you must always use the formula ir + a + infinitive verb. You cannot say vas viajar; the a is the grammatical glue that holds the phrase together.
