Commonwealth of Independent States; putative successor to the USSR, except that the Baltic Republics of Estonia, Latvia, and Lithuania never joined. Contrary to another definition of CIS at the Urban Dictionary, the CIS does not stand for "Communist Independent States." Moreover, that definition has the CIS existing BEFORE 1991, and includes Kazakhstan as "not officially part of the Soviet Union." Kazakhstan was, in fact, one of the 15 republics of the USSR until 1991.

The CIS came into being December 1991. Mostly consists of regularly scheduled conferences of foreign ministers and defense ministers.

In 1995, members Belarus and Russia created the Commonwealth of Sovereign Republics (CSR).
The August 2008 war between Georgia and Russia was unique in being a direct war between CIS member states, although there have been others waged by proxy.

CIS is an abbreviation for the term "Collective Information Source".

A collective information source is an educational resource with information specific to a certain subject; it is usually held in a binder or folder.

A CIS can be created for general educational purposes, as a place to gather ones arguments during a disagreement, or out of pettiness.

This abbreviation is not to be confused with any of the following:
Cisgender, The Center for Immigration Studies, The Commonwealth of Independent States, The Council of International Schools, The Center for Internet Security, Canadian Interuniversity Sport, The Corpus Inscriptionum Semiticarum, Carcinoma in situ, The Center for Comparative and International Studies, The Knabenchor collegium iuvenum Stuttgart, a continuous ink system, a copper indium selenide solar cell, a contact image sensor, The Confederacy of Independent Systems, the towns in Italy and Poland, the mathematical function, the Cis beetle, cis regulatory elements, cis isotope alkenes, cisalpine, and the C# music note.

A made up stupid tranny term used by the gender switch folks community to describe normal people that are not confused about their pronouns/gender identity. It's especially very insulting, since it's NOT us that are changing and mutilating our genitals to adapt to them...they ARE the ones changing and transforming to adapt to US.
These hypocrites want others to respect their pronouns..yet they don't wanna respect our pronouns. They wanna be called "women" but wanna call real women "cis" and get offended if we used the term "real" cause it would be "TRaNspHopiC"
I'm not a "cis" woman..I'm a woman.
I don't need a prefix to describe who NATURALLY I am....a woman.
