noun
maturity
muh-CHOOR-uh-tee/məˈtʃʊrəti/
The attainment of full development.
At maturity, the butterfly rests with open wings beside its empty chrysalis.

Etymology
The pieces express the state of being ripe. English uses that completeness for both natural development and character, so maturity can concern adult growth or fully developed judgment.
In context
Most countries recognize 18 as the start of adulthood by granting various freedoms and privileges. But is age the best way to measure maturity?
