'age-limited' originates from the combination of 'age' and 'limited', where 'age' refers to the length of time a person has lived or a thing has existed, and 'limited' means restricted in size, amount, or extent.

'age-limited' evolved from the concept of 'age limit', which has been used to denote restrictions based on age.

Initially, it meant 'restricted by age', and this meaning has largely remained the same in modern usage.
