Which word means to secure, support, strengthen or fasten from underneath?

• A. Invoke
• B. Denouement
• C. Undergird
• D. Traction

Answer: (C)

Securing or strengthening from below is about providing a firm foundation, and the verb that captures this precisely is undergird. Undergird means to support, reinforce, or secure something from underneath; to gird beneath to strengthen the base. This exact sense matches the idea of securing or fastening from underneath. The other words don’t fit: invoke is about calling upon or appealing to someone or something; denouement is the ending or resolution of a story; traction refers to grip or progress, not the act of supporting from below. For example, engineers undergirded the bridge with steel beams to reinforce its foundation.
