¿Cuál es la diferencia entre until before noon y until noon y before noon y ex) I ate only fruit until before noon. ?Puedes dar oraciones como ejemplo.

I will be using your example sentence to explain.
Before noon means any time before 12 in the afternoon. “I ate fruit before noon, so around 8:30 in the morning.” Until noon means at 12. “I ate fruit around 12 for lunch time.” Until before noon would be used if you don’t have a specific time an event occurred and are just speaking generally of any time before 12 in the afternoon, so this could be used interchangeably with “before noon.” It sounds more natural to used “before noon” without the until. “I was craving fruit but I waited until before noon to eat fruit.”

Hope this helps! I’m happy to answer any more questions
