The term 'assembly members' refers to a group of individuals who come together to form a governing body, such as in the case of a legislative or parliamentary body. Antonyms for this term would include words that describe the opposite of this group dynamic - such as solitary, single, individual, or isolated. These words would suggest a situation where there is only one person making decisions or taking actions, rather than a collective body. While there are certainly situations where a single individual may have the authority to make decisions on behalf of a group, the term 'assembly members' specifically implies a larger, organized group working together towards a common goal.
