Etymology Origin:
The word fulcrum originates from Latin fulcrum, which referred to the "bedpost" or "support of a couch." Over time, its meaning narrowed to the pivotal point of a lever in mechanics, reflecting the idea of a foundational support enabling movement. The suffix -um solidifies its role as a tangible object. The logic mirrors how physical support (fulcrum) translates metaphorically to a central enabler in abstract contexts.
