Sense: noun/1
All four words name natural materials used in construction and design, but they differ in hardness, appearance, and typical use. Granite is the hardest of the group, with a visibly grainy or crystalline texture caused by slow cooling of magma underground. Stone is the broadest term — it can refer to any hard, non-metallic mineral material, from pebbles to cut building blocks. Rock is even more general than stone in geology (any naturally occurring solid mineral mass), but in everyday speech, 'rock' and 'stone' overlap. Marble is a metamorphic rock that forms when limestone is subjected to heat and pressure; it is softer than granite, develops vein patterns rather than crystals, and is more commonly used for indoor sculptures and luxury floors. Slate is a fine-grained metamorphic rock that splits easily into thin sheets, making it popular for roofing tiles and chalkboards. For a kitchen worktop that resists scratching and heat, granite is the practical choice; marble would stain and scratch more easily, while slate is too brittle for a horizontal surface.

Etymology
Granite entered English in the 17th century from Italian 'granito', meaning 'grained', because the stone has a visible granular texture made of interlocking mineral crystals. The Italian word comes from Latin 'granum' (grain or seed). The name originally described the appearance rather than the geological composition of the rock.
