Covered with or made of concrete; having a concrete surface or being solidified into concrete form.
From Latin 'concretum' (grown together, solidified), past participle of 'concrescere.' The modern term specifically refers to the building material concrete, which solidifies by binding particles together.
It's fascinating that 'concrete' as a building material is named after this ancient Latin word for 'grown together'—because concrete literally works by particles bonding and growing into solid mass, just like the original Latin meaning.
