Etymology
The word 'foursquare' is a compound formed from the cardinal number 'four' and the geometric term 'square'. Its literal, architectural sense refers to a building or structure that is solidly built on a square plan with four equal sides. This inherent sense of solidity, stability, and right-angled integrity was metaphorically extended to describe character and action. By the 16th century, it had evolved to describe a person who is morally upright, steadfast, and unwavering, much like a solid, squarely-built edifice. The adverbial use, meaning "firmly and resolutely," follows naturally from this adjectival sense of unwavering solidity.
