'antsy' originates from the English word 'ant,' where 'ant' refers to the insect known for its constant movement.

'antsy' evolved from the colloquial use of 'ant' to describe someone who is unable to stay still, eventually becoming the modern English adjective 'antsy.'

Initially, it referred to someone who was 'as restless as an ant,' and over time it evolved into its current meaning of 'feeling restless or impatient.'
