IPA: /tɛˈrɛlə/
KK: /tɛˈrɛlə/
A small model of the Earth or a celestial body, often used for educational purposes.
The teacher used a terrella to demonstrate the Earth's rotation and revolution around the sun.
The word 'terrella' comes from Latin 'terra' (meaning earth or land) and the diminutive suffix '-ella' (meaning small or little). Therefore, 'terrella' refers to a small earth or a small globe, often used in a scientific context to describe a model of the Earth.
Think of 'terra' meaning earth and '-ella' meaning small — so a terrella is like a little model of the Earth.
