The part people get wrong

Often misspelled as thermostate or thermostatn.

Same family: thermostatic, thermostatically, thermometer, temperature, heating. If you can spell one, the shared part carries to the others.

Where it comes from: Thermostat comes from two Greek roots: 'thermo' meaning 'heat' and 'stat' meaning 'standing' or 'keeping steady.' So a thermostat is literally a device that keeps the heat steady.
