A butment, also known as an abutment, is an essential architectural feature that provides support or reinforcement for various structures such as bridges, arches, or retaining walls. Its purpose is to resist the horizontal forces exerted by the load and transfer them safely to the ground while maintaining stability. While the word "butment" is commonly used, there are several synonyms that also describe this structural element, such as support, foundation, base, pillar, or footing. These terms highlight the core function of a butment, underscoring its vital role in ensuring the structural integrity and durability of various constructions.
