padding

The word 'padding' originates from the verb 'pad', which emerged in the 16th century meaning to stuff or fill out with soft material. This verb is likely related to, or derived from, the noun 'pad' referring to a soft cushion or bundle of straw, itself traceable to Low German or Dutch words for a path or the sole of the foot—concepts associated with a soft surface to tread upon. The addition of the '-ing' suffix, a productive nominalizer from Old English, transformed the action into a noun denoting the material used for stuffing or the result of the action. Over time, the meaning extended metaphorically to describe superfluous content in language or data, maintaining the core idea of adding soft, often unnecessary, filler.
