Definition
A small to medium-sized lizard with a flattened body, large forward-facing eyes, and adhesive toe pads that allow it to climb smooth surfaces and even walk on ceilings. Geckos are found on every continent except Antarctica and are known for their vocalizations and unique hunting behavior.
Example Usage
The house gecko darted across the wall with remarkable speed, its sticky feet never losing grip on the smooth plaster.
Origin
From Malay 'gekok,' an onomatopoetic word mimicking the sound these lizards make, used across Portuguese and Dutch traders before entering English.
Fun Fact
Gecko toe pads work through van der Waals forces—the same atomic attraction that makes molecules stick together—allowing them to support their weight without any glue or moisture needed.
