Questions & Answers about ¡Que tengan una gala fenomenal!
Why does this sentence start with Que?
Starting a sentence with Que followed by the subjunctive is a common way to express a wish or a hope for someone else. It is a shortcut for saying Espero que... (I hope that...) or Deseo que... (I wish that...). So, this essentially means '[I hope] that you have a phenomenal gala!'.
Why is the verb tengan instead of tienen?
Because it follows the independent que used for wishing. Whenever you use this Que + [verb] structure to wish someone well, the verb must be in the subjunctive mood. Tengan is the present subjunctive form of the verb tener.
Who is being spoken to in this sentence?
Gala is feminine, so why doesn't fenomenal end in an a?
