The intermediate state refers to the period between two events or stages. Some synonyms for this term include transitional phase, interim period, middle ground, in-between state, and the halfway point. The transitional phase indicates a time of change or adjustment, while the interim period suggests a temporary space before the next stage. Middle ground describes a balance between two extremes, and the in-between state refers to a state that is neither one thing nor the other. Finally, the halfway point indicates that something is halfway through a process. Each of these synonyms helps to convey the idea of the intermediate state and its transitory nature.
