The antonym for the word "more curbed" is "less curbed." This means that something is less restrained or restricted. The opposite of curbed is unbridled, wild, or unrestricted. When something is less curbed, it has more freedom or flexibility to act or move in a certain direction. For example, if someone's behavior is less curbed, they may act more impulsively or recklessly. On the other hand, if their behavior is more curbed, they may be more cautious or inhibited. Ultimately, the level of curbing depends on the situation and the individual's personality and values.
