The term 'LARGE STONE' can be solved by the word 'ROCK', which is a four letter word. A ROCK is a naturally occurring solid aggregate of one or more minerals or mineraloids. Rocks are usually hard and rigid, and they come in various sizes, ranging from small pebbles to large boulders. Rocks are found on Earth's surface and beneath it, and they are used for many purposes, such as construction, landscaping, and jewelry.
