stammer (v.): Old English stamerian "to stammer," from Proto-Germanic *stamro- (cognates: Old Norse stammr "stammering," Old Saxon stamaron, Gothic stamms "stammering," Middle Dutch and Dutch stameren, Old High German stammalon, German stammeln "to stammer," a frequentative verb related to adjective forms such as Old Frisian and German stumm "mute"). Related: Stammered; stammerer; stammering; stammeringly.
stumble (v.): c. 1300, "to trip or miss one's footing" (physically or morally), probably from a Scandinavian source (compare dialectal Norwegian stumla, Swedish stambla "to stumble"), probably from a variant of the Proto-Germanic base *stam-, source of Old English stamerian "to stammer," German stumm, Dutch stom "dumb, silent." Possibly influenced in form by stumpen "to stumble," but the -b- may be purely euphonious. Meaning "to come (upon) by chance" is attested from 1550s. Related: Stumbled; stumbling. Stumbling-block first recorded 1526 (Tindale), used in Rom. xiv:13, where usually it translates Greek skandalon.
