Interest can also be the care or concern that someone has for something or someone. If someone cares about something, they "have an interest" in that thing, or they "find it interesting". If something is beautiful, or funny, or new, that might make the thing interesting. However, a very important concern, for example love or hate, is more than an interest. An interest can also be a task that someone likes to do or watch, like a game or a hobby.
