Noun
pl: restraints
This term describes a tension between an impulse and a boundary. When applied to behavior, it suggests a conscious, disciplined effort to suppress an emotional reaction or a desire, often implying a sense of maturity or stoicism.
In a physical or systemic sense, it refers to a hard limit or a mechanical barrier. While the abstract sense is often praised as a virtue, the physical sense can carry connotations of coercion or necessary safety measures.
