Origin
Derived from Latin 'scala', meaning ladder or staircase. The term evolved to describe quantities that can be measured solely by magnitude, analogous to the linear progression of a ladder's rungs.
Breakdown
scala (ladder, scale) + -ar (adjective suffix meaning 'relating to' or 'of the nature of'), producing a word describing something having the quality of a single-dimensional scale or magnitude.
