adjective / noun
maximum
MAK-sih-muhm/mˈæksʌmʌm/
The greatest amount or level possible in a given context.

Etymology
Latin maximus means “greatest,” the superlative of magnus, “great.” Its neuter form supplies the noun for the greatest amount or degree—the upper limit rather than merely something large.
In context
out of pocket is the amount of money that you pay. This includes your copays, doctor's visits, co-insurance, deductibles, drugs, and the out-of-pocket maximum is your plan's cap
