mature adult
No longer young
A mature adult is someone who has reached full physical development and, more importantly, demonstrates emotional stability, responsibility, and sound judgment.
The phrase is often emphatic or redundant—adult alone implies maturity—so it typically appears when distinguishing genuinely responsible adults from those who are merely grown: We need mature adults to handle this situation, not hotheads.
In age-restricted contexts, mature adult sometimes serves as a euphemism for content intended for older audiences.
