The word "painless" combines "pain" (from Old French peine, Latin poena meaning "penalty" or "suffering") with the suffix "-less" (Old English -lēas, meaning "without"). The suffix "-less" negates the root, transforming "pain" into "without pain." This logical construction reflects a straightforward evolution from physical suffering to its absence, later extending metaphorically to describe tasks or experiences requiring no effort.
The dentist promised a painless procedure.
She found the exam painless due to thorough preparation.
Modern vaccines are nearly painless.
His painless humor made the lecture enjoyable.
The software update was quick and painless.
