Final answer:
An antonym for yielding could be inflexible, stubborn, or unyielding, describing someone or something that does not easily give in or change.
Step-by-step explanation:
The antonym for yielding is inflexible, stubborn, or unyielding. Yielding implies being flexible, compliant, or ready to give way under pressure. In contrast, an inflexible or stubborn person or object doesn't easily give in or change their stance. When someone is unyielding, they stand firm in their opinions or actions despite any opposition or persuasion attempt. For instance, a yielding material might bend or fold when force is applied, whereas an inflexible material would maintain its shape.
