KK: /ˈbaɪˌpɛdəlɪzəm/
The ability or condition of walking on two feet instead of four or more.
Humans are known for their bipedalism, which allows them to walk upright.
Bipedalism → It is formed from "bi-" (meaning two) and "pedalis" (from Latin "pes", meaning foot). The word describes the condition of walking on two feet.
Think of 'bi-' meaning two and 'pedal' relating to feet — this helps you remember that bipedalism refers to walking on two feet.
