Final answer:
The opposite of 'virile' is 'womanly', which relates to qualities traditionally considered feminine. This is in contrast to 'virile,' which is associated with traditionally male traits.
Step-by-step explanation:
The opposite of virile is womanly. The word 'virile' is often associated with qualities traditionally ascribed to men, such as strength and vigor. In the 1971 study by Broverman and Broverman, characteristics attributed to males included aggressive, rough, and active, while female traits included unaggressive, gentle, and passive. Based on these associations, 'womanly' would be the antonym of 'virile' as it pertains to qualities that are traditionally considered feminine.
