👉 The term "once fluid" refers to a state where something has been in a continuous, uninterrupted condition without significant change or transformation. It suggests a time when elements were seamlessly integrated, harmonious, and free from disruption or division. For instance, a once fluid ecosystem might have had all its components working together in perfect balance, whereas a once fluid society would have had its social, political, and cultural elements intertwined without clear boundaries or conflicts. This concept implies a period of unity and cohesion that has since changed or evolved, leaving behind remnants or traces of its former state.
