Have you noticed how the seasons change imperceptibly?

Yeah, one day it just feels different, doesn’t it?

Root Explanation

Imperceptibly → It is formed from "im-" (meaning not) and "perceptible" (from Latin "perceptibilis", meaning able to be perceived, from "percipere", meaning to seize or take in). The word "imperceptibly" means in a manner that cannot be perceived or noticed.

Memory Tip

Think of 'not' ('im-') being able to be 'noticed' ('perceptible') — that's why imperceptibly means something that happens so subtly that you can't notice it.
