Regime

Technically the word "regime" (occasionally spelled "régime", particularly in older texts) refers to any system of control, or more specifically a system of government, but in English language it has become a largely pejorative synonym for "government" or "administration", implying moral disapproval and/or political opposition.

Thus one can speak of "the vicious oppressive regime of Borduria"; but seldom of "the regime in Washington" or of "the current Blair regime".

Compare: Ancien régime, Bush regime, Vichy regime, regime change

simple:Regime

A less pejorative usage occurs in set phrases such as exercise regime or medical regime. Compare regimen.

In science, a regime can mean a particular state of affairs where a particular physical phenomenon or boundary condition is significant, such as "the superfluid regime" or "the steady state regime".
