Final answer:
The NASW definition from 1973 outlines social work as a profession aimed at helping individuals and communities improve their social functioning, though the exact wording from 1973 isn't provided here. The NASW has continued to evolve its definitions to match contemporary standards.
Step-by-step explanation:
The NASW (National Association of Social Workers) definition of social work, as stated in their 1973 code of ethics, describes social work as a professional activity of helping individuals, groups, or communities enhance or restore their capacity for social functioning and creating societal conditions favorable to this goal. While the 1973 definition is not provided here, NASW has a rich history of advocating for social justice and supporting the welfare of individuals through the standards and ethics that define the profession.
It is crucial to note that the NASW has updated its definitions and ethical guidelines over the years to reflect current professional standards and societal changes; the most recent definition can be found in their current literature and official website.
