'smudge-resistant' originates from the combination of 'smudge' and 'resistant', where 'smudge' refers to a smear or stain and 'resistant' means able to withstand or prevent.

The term 'smudge-resistant' evolved from the need to describe materials or surfaces that could withstand smudging, particularly in the context of technology and household items.

Initially, it meant 'able to resist smudging,' and this meaning has largely remained the same in modern usage.
