Which root means heat?

Which root means heat?

• A. PSYCH
• B. PY
• C. SEPS
• D. THERM

Answer: (D)

Heat is described by the root therm- (often seen as therm- or thermo-). This form appears in many terms related to temperature and warmth, such as thermometer, thermal, and thermodynamics, which is why it’s the correct choice for meaning heat. PSYCH refers to the mind or soul, as in psychology, so it doesn’t convey heat. SEPS is tied to decay or infection (as in sepsis), not temperature. The fragment PY isn’t the standard root for heat and is more associated with fire in other forms (like pyro/pyr), not heat itself.
