The word "more withstanding" implies resistance or durability. Its antonyms are words that connote fragility or weakness, such as delicate, fragile, frail, and tender. Other antonyms are words that suggest surrender or submission, such as capitulation, acquiescence, yielding, and compliance. The opposite of "more withstanding" could also be words that suggest being overwhelmed or overpowered, like defeated, subdued, conquered, or vanquished. When faced with adversity, it is human nature to want to be more withstanding. But it is important to remember that embracing vulnerability, and understanding our limitations, can also be a sign of strength.
