solid = sol<whole> + id<adjective suffix>
- sol (from Latin solidus, meaning "whole, firm, dense")
- id (a suffix forming adjectives, often indicating state or quality)
Etymology Origin:
The word solid traces back to Latin solidus, which originally meant "entire, undivided, or dense." This reflects the core idea of something being firm or unbroken. Over time, solidus evolved into Old French solide, and later into Middle English solid, retaining its meaning of physical firmness while expanding metaphorically to denote reliability (e.g., "solid argument"). The suffix -id was adopted from Latin to form adjectives describing inherent qualities.
