hack

Etymology 1

From Middle English hacken, hakken, from Old English haccian (“to hack”), from Proto-West Germanic *hakkōn, from Proto-Germanic *hakkōną (“to chop; hoe; hew”), from Proto-Indo-European *keg-, *keng- (“to be sharp; peg; hook; handle”). Cognate with Saterland Frisian häkje (“to hack”), West Frisian hakje (“to hack”), Dutch hakken (“to chop up; hack”), German hacken (“to chop; hack; hoe”), Danish hakke (“to chop”), Swedish hacka (“to hack; chop”), French hacher (“to chop”). The computer senses date back to at least 1955 when it initially referred to creative problem solving. By 1963, the negative connotations of “black hat” or malicious hacking had become associated with telephone hacking (cf. phreaking).
