A legislature is a group of people elected to make laws that benefit all citizens. The word legislature is closely related to the word legislator, which is why the terms are commonly confused. A legislator is an individual person who makes laws. An organized group of legislators working together makes up a state's or country's legislature.
The Latin root of legislature is legis, which means "law," and that's what a legislature is all about — making laws, amending laws, or repealing laws. Here are a couple of examples that illustrate this point:
The seventh congressman to vote was Harry Burn, twenty-four, the youngest member of the legislature. (Votes for Women!)
Tuesday's off-year votes will determine who governs two US states, and which party will control state legislatures in others. (BBC)
The word legislator combines the Latin root legis with the root lator, which means "a proposer." So, a legislator is an individual who proposes laws, as shown in the following examples:
Across the country, legislators were grappling with whether to regulate cell phone use by drivers. (A Deadly Wandering)
During the 2022 session, legislators enacted a plan to reduce the state income tax over four years — Mississippi’s largest tax cut ever. (The Washington Times)
Once elected, each individual legislator works together as one legislature to make and shape laws. This in turn contributes to the stability, development, and well-being of a society.
