Etymology

From Middle English melten, from a merger of Old English meltan (intransitive) and mieltan (transitive), both meaning “to melt, digest,” from Proto-West Germanic meltan and maltijan, from Proto-Germanic meltaną and maltijaną, both from Proto-Indo-European *(s)meld- (“melt”). Cognate with Icelandic melta (“to digest”).
