✕Common Mistakes
Que buena idea!
Missing accent changes "qué" (how) to the conjunction "que" (that).
¡Qué buena idea
Spanish requires both opening and closing exclamation marks.
¡Muy buena idea!
Using "muy" changes the nuance; it’s correct grammar but no longer an exclamation of surprise.

Cultural Tip
Exclamations are very common in everyday Spanish and often sound more animated than their English equivalents. Remember to keep the accent on "qué"; without it the word becomes the conjunction "que" (that). Also, the intensity can be softened with "muy" (muy buena idea) but you lose the spontaneous, surprised tone that "¡Qué...!" gives.
