The word "more unpermissive" refers to a strict or stringent attitude towards rules or regulations. Its antonyms include lenient, permissive, indulgent, easygoing, flexible, and tolerant. These words suggest a more liberal and relaxed approach to adhering to set guidelines, allowing for greater freedom and flexibility in decision-making. In a world where things are constantly changing, being flexible and tolerant can be beneficial for making changes to adapt to the situation.
