product
Something that is made or created, or a result.
A product is something that gets made or created, whether by people, machines, nature, or even ideas working together. When a factory manufactures smartphones or a bakery produces fresh bread, those items are products. When a farmer grows wheat or bees make honey, those are products too.
In mathematics, a product means something different: it's the answer you get when you multiply numbers together. The product of 6 and 7 is 42. When you're solving a multiplication problem, you're finding the product.
A product can be physical, like a bicycle or a book, or less tangible, like software or a song. Companies spend enormous effort designing, testing, and improving their products to make them useful and appealing.
When something is the product of hard work, that means hard work created it or made it possible. Your improved piano skills might be the product of daily practice. A beautiful garden is the product of careful planning, watering, and weeding. In this sense, product describes not just manufactured items but any result that comes from effort, time, or natural processes working together.
