Morphology

buffer = buff (semi-transparent) = buff + er

The chemistry sense is a technical metaphor: a 'buffer' resists or moderates change, which extends the general sense of 'to buffer' but requires domain knowledge.

Etymology

Buffer comes from the old idea of buff meaning 'to soften a blow' or 'protect'. In chemistry, a buffer is a substance that acts like a 'cushion' to keep the pH steady.
