1. The differences in meaning: The word “problem” is connected with the word “solution” Some bad things that happen can't be called "problems" because they're unsolvable. For example, if you broke your leg, you probably wouldn't call your broken leg a "problem". "Trouble" is less connected to solutions. It's more connected to negative feelings that you get when bad things happen. "Issue" is associated with difficult decisions and disagreements. We use "issue" in a similar way to "problem" or "trouble", but it also has another meaning. It can mean a topic that people are talking about or disagreeing on. Social issues and political issues are examples of this kind of "issue". 2. Collocation using: · "Problem" is used more than "trouble" or "issue".
