Watch for double o.
Same family: ceiling (as a synonym in the sense of limit), cap (as a synonym in the sense of limit), upper-limit, maximum, threshold. If you can spell one, the shared part carries to the others.
Where it comes from: In finance and economics, the word “roof” is sometimes used metaphorically like “ceiling” to describe an upper limit on prices, wages, or spending, extending the original idea of a physical roof as the highest point of a building.
