Questions & Answers about El equipo imparable va a triunfar.
What is the root of the word imparable?
Why use va a triunfar instead of the simple future tense triunfará?
Both are grammatically correct and mean practically the same thing. However, in spoken Latin American Spanish, the informal future (ir a + infinitive) is used much more frequently than the simple future tense (triunfará) to state what is going to happen, especially when it feels like a guaranteed certainty.
Is there a difference between triunfar and ganar here?
Yes, a slight stylistic one. Ganar simply means to win (like winning a specific match). Triunfar means to triumph or to succeed, which gives a more epic, absolute, or long-term feeling to the team's success.
