equilibrium
/ɛkwɪˈlɪbɹɪəm/
equilibrium means the condition of a system in which competing influences are balanced, resulting in no net change.
equilibrium is pronounced /ɛkwɪˈlɪbɹɪəm/.
Why “equilibrium” is a great word
A state in which opposing forces or influences are balanced, resulting in stability and no net change. From Latin aequilībrium, from aequus ("equal, level") + lībra ("balance, scales"), first recorded in English c. 1600. Unlike "balance" (which often implies a static, even distribution) or "stasis" (which suggests a total standstill), equilibrium denotes a dynamic system where opposing changes occur at equal, canceling rates. It is the trembling point of a tightrope walker's body in motion, the constant temperature of a room where heat loss matches heat gain, or the chemical dance in a sealed vial where decomposition and synthesis proceed at identical paces—the fragile, active calm that is the universe's most temporary and necessary fiction.
Etymology
From Latin aequilībrium, from equal + lībra (“balance”).
noun
- The condition of a system in which competing influences are balanced, resulting in no net change.
- Mental balance.e.g.“Tiffany Pollard: What just happened?!

Tiffany Pollard: I can't take this. This is gonna mess up my equilibrium.”
- The state of a reaction in which the rates of the forward and reverse reactions are the same.
- The state of a body at rest or in uniform motion in which the resultant of all forces on it is zero.
