Etymology
The word "percent" is a direct loan from the Latin phrase "per centum," which translates literally to "by the hundred." This phrase was used in Medieval Latin commercial documents to denote rates of interest or proportion. The term entered English in the 16th century, initially in the full Latin form, before being shortened to its current single-word spelling. Its logic is purely mathematical, preserving the original Latin concept of calculating a proportion out of a base of one hundred, a system that remains the standard for expressing ratios and percentages today.
