Other forms: recommendations
If you give someone a recommendation, you're saying, "try this, it's good" or "this is the best way to proceed," or "this person will do a great job."
The noun recommendation stems from the Middle Latin word recommend, meaning "praise" or "present as worthy." Policy makers have made a strong recommendation to implement renewable energy initiatives to alleviate our dependence on fossil fuels. It used to be that you carried a letter of recommendation from a prominent person and used it as an introduction to polite society in an unfamiliar place, but nowadays, such a letter simply explains why someone is qualified for a particular job or school.
