accident
The word 'accidentado' in Spanish refers to a state or event that is uneven, rugged, or, in some contexts, it can also refer to an unfortunate occurrence that happens unexpectedly and unintentionally, typically resulting in damage or injury, which in English is generally referred to as an 'accident'. However, it is more frequently used to describe terrain, roads, or landscapes that are irregular or difficult due to natural formations.
