While the words "problem" and "issue" are often used interchangeably, there are subtle differences between them. A "problem" usually refers to a situation that is difficult, unpleasant, or requires a solution. It often implies something that needs to be fixed or resolved. An "issue" is a subject or matter that needs to be discussed, considered, or decided. It often implies something that requires attention or action but doesn't necessarily need to be fixed.
Think of it this way: a problem is something that needs to be solved, while an issue is something that needs to be addressed. A broken phone is a problem, you need to fix it. Climate change is an issue, we need to discuss solutions.
Here are some example sentences to illustrate the difference:
Notice how "problem" suggests a difficulty that needs fixing, whereas "issue" points towards a matter requiring attention or discussion. The context often dictates which word is more appropriate to use.
