The phrase "most strongminded" implies an individual who possesses a strong will, determination, and a firm resolve. Antonyms for this phrase would include "weak-willed," "indecisive," "spineless," "impressionable," and "malleable." These individuals lack the conviction and tenacity to stick with their moral principles and succumb quickly to external influences. People who are weak-willed are easily manipulated, and their decisions often lack conviction. They may be swayed by external factors such as peer pressure, social norms, or propaganda. In contrast to the "most strongminded," these individuals may struggle to assert themselves in challenging situations and are easily coerced.
