Conversation

Have you ever heard of hyperacuity?

I think so, isn’t it about having really sharp senses?

Yeah, exactly! It's when your sensory performance is even finer than usual.

That sounds fascinating, I wish I could experience hyperacuity like that!

Root Explanation

Hyperacuity → It is formed from "hyper-" (meaning over or beyond) and "acuity" (from Latin "acuitas", meaning sharpness or keenness). The word describes a condition of having an exceptional sharpness of perception or vision, going beyond normal acuity.

Memory Tip

Think of 'hyper-' meaning 'beyond' and 'acuity' referring to 'sharpness' — this helps you remember that hyperacuity means having an extraordinary sharpness of perception.
