buffer = buff<to soften or lessen> + er<agent noun suffix>
- buff (from Old French buffe, meaning "a blow" or "to soften by striking," later generalized to "lessen impact")
- er (agent suffix indicating "one who does or thing that performs an action")
Etymology Origin:
The word buffer originated in the 16th century from the verb buff, meaning "to soften a blow." Over time, it evolved to describe physical cushions (e.g., railway buffers) and later metaphorical or technical buffers (e.g., data buffers). The suffix -er turns the action into a noun, creating the sense of "something that softens or protects."
