Bicameralism

noun (uncountable)

/baɪˈkæmərəlɪzəm/

A system of legislature divided into two distinct chambers or houses, typically an upper house and a lower house. India's Parliament is bicameral under Articles 79–122, comprising the Lok Sabha (lower house) and Rajya Sabha (upper house); six state legislatures are also bicameral, consisting of a Vidhan Sabha and a Vidhan Parishad. The rationale is to combine direct popular representation with a deliberative revising chamber.

✍️ Usage in a UPSC answer

The rationale for bicameralism in India rests partly on federalism—the Rajya Sabha representing the states—and partly on the deliberative value of a revising house that can check the populist impulses of the directly elected Lok Sabha.

🔡 Root

Latin bi- (two) + camera (chamber, vault) ← Greek kamara (vaulted room)

📜 Etymology

Formed in the 19th century from the Latin prefix bi- (two) and camera (chamber), with the suffix -ism denoting a political system. The word entered political science vocabulary as European and American constitutions debated upper-house design; it was popularised in English by constitutional theorists of the 1860s–1890s.

🧠 Memory Hook

BI = two, CAMERA = chamber: BICAMERALISM = two-chambered. Think of the BICYCLE — bi (two) wheels — applied to the legislature's two chambers (cameras).
