Etymology

From Middle English lacchen (“to seize, catch, grasp”, verb), from Old English læċċan (“to grasp, take hold of, catch, seize”), from Proto-Germanic *lakjaną, *lakwijaną, *lakkijaną (“to seize”), from Proto-Indo-European *(s)leh₂g-, *(s)leh₂gʷ- (“to take, seize”). Cognate with Middle Dutch lakken (“to grasp, catch”).
