Morphology
imperceptible = perceptible (transparent) = im + percept + ible
Formed by the negative prefix 'im-' + 'perceptible' ('able to be perceived'), so the meaning 'not able to be perceived' follows directly.
Etymology
The word imperceptible begins with im- ('not') and the rest comes from the common verb perceive ('to notice' or 'to feel'). So imperceptible means 'not able to be noticed' or so small you cannot feel it.
