Explanation
The word concern has several uses. First, it means worry or care about something. For example, parents show concern for their children’s safety. Second, it can mean something important or related to someone. For instance, “This matter concerns everyone.” As a noun, concern means a worry or an important matter; as a verb, it means to affect or worry someone or to worry or care about something. In business, concern can also mean a company or organisation. For example, “He runs a successful business concern.” So, the word is flexible: it shows feelings, importance, responsibility, or even a business organisation.
