From back + -ing. back comes from Middle English bak. From Middle English bak, from Old English bæc, from Proto-West Germanic bak, from Proto-Germanic baką, possibly from Proto-Indo-European bʰeg- (“to bend”). The adverb represents an aphetic form of aback. Compare Middle Low German bak (“back”), from Old Saxon bak, and West Frisian bekling (“chair back”), Old High German bah, Swedish - and Norwegian bak. Cognate with German Bache (“sow [adult female hog]”).
