A more thorough explanation:

SISTREN

Sistren is a noun that refers to sisters, particularly those who are considered spiritual kin, such as female colleagues on a court. It is similar to the term "brethren" which refers to male colleagues.

• As a member of the sorority, I consider all my fellow sisters to be my sistren.
• The female judges on the court were referred to as sistren by their male counterparts.

These examples illustrate how the term "sistren" is used to refer to female colleagues who share a spiritual or professional bond. It is a term of respect and camaraderie, emphasizing the importance of sisterhood and solidarity among women.
