neutermost

This term is a superlative adjective used primarily in technical, scientific, or geometric contexts to describe the absolute limit of a spatial arrangement relative to a center. It carries a precise, clinical tone and is rarely used in casual conversation.

Because it is a superlative form, it describes a unique position within a specific system. It is often used in physics or chemistry to describe the outermost shell or boundary of a particle or structure, emphasizing the maximum distance from the core.
