Antonyms for the phrase "attaining majority" include "not reaching adulthood," "remaining a minor," "stunted growth," and "forever immature." These opposing terms imply that a person hasn't reached the age of majority, has not gained legal rights, privileges, and responsibilities of adulthood. Alternatively, they suggest someone is limited in their emotional or intellectual maturity, or has failed to achieve independence and individual autonomy. While some may view not attaining majority as a negative or unfortunate state, others may see it as an opportunity to continue growing and developing essential life skills before facing the challenges of adulthood.
