conundrum

A conundrum is a confusing or puzzling problem that can't easily be solved. It's like trying to figure out a tricky riddle.

People often use this word when talking about complex issues that seem impossible to fix. For example, if you're stuck on a puzzle and just can't think of the answer, it might be called a conundrum. In politics or business, someone might say they're facing a conundrum because they have to balance different priorities at once, like making money while also being environmentally friendly. Some people use this word even when talking about everyday life - if you're deciding what to wear and can't decide between two outfits that both seem perfect, it could be considered a small-scale conundrum!
