means A molecule made of many amino acids linked together in a chain by peptide bonds — the basic structural string that folds up into (or forms part of) a protein.

from Built from Greek parts: 'poly-' meaning many, and 'peptide,' which traces to 'peptos,' meaning cooked or digested — from 'peptein,' to digest or ripen. The link to digestion makes sense: peptides were first understood through the breakdown of proteins, so the pieces left over from that 'cooking down' process borrowed the name. 'Polypeptide' simply scales it up — not one digested fragment, but many amino acids strung in a row.
