BUF-uh/ˈbʌfə/

A buffer is something that reduces the shock of a change or blow: a buffer against inflation, a buffer zone. Cushion is a close everyday cousin; shield is stronger. In computing, a buffer stores data temporarily. In speech, something that softens the blow is enough. Railway buffers stop a train at the end of the track — the physical picture behind the metaphor. Do not call a friend a buffer unless you mean they absorb the row.
