A difficulty is anything that causes problems. Forgetting an answer during a test could be a difficulty. A broken leg is a more painful difficulty. A poor economy is a difficulty, and losing your job is a more personal difficulty. A difficulty is also anything that’s not easy to do, like becoming a doctor or lifting a huge weight. Difficulties are generally serious or hard to overcome. If you’re having difficulty, you’re having troubles.
