Corpus data places it at rank #15,203 in overall English word frequency, marking it as uncommon enough that many writers pause before typing it.Wiktionary records 14 distinct senses for this headword, so context determines which meaning a reader should apply.
Our Hunspell-derived misspelling index lists 6 documented wrong-spelling variants for knob, with forms such as "kknob", "knbo", and "knnob". Each variant represents a distinct typo pattern that appears often enough in corpora to be worth flagging, typically a doubled-consonant error, a silent-letter drop, or a vowel substitution.It also participates in 20 confusable-pair relationships, "ko", "Koh", "koi", and more, where similar look or sound leads writers to substitute one word for another in context.
Etymologically, the entry records: From Middle English knobbe, from Middle Low German knobbe (“knob, knot in wood, bud”), probably ultimately from a variant of Proto-Germanic *knappô (“knob, lump”), one of several kn- words related to *knudaną (“to knead”). Compare Middle Dutch knobbe, cnopp… Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is knob, spelled K-N-O-B, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.

Etymology
From Middle English knobbe, from Middle Low German knobbe (“knob, knot in wood, bud”), probably ultimately from a variant of Proto-Germanic *knappô (“knob, lump”), one of several kn- words related to *knudaną (“to knead”). Compare Middle Dutch knobbe, cnoppe, Middle Low German knobbe (“knob, knot in wood”), knubbe, Dutch knop (“knob, button, bud”), Old Frisian knopp, knapp, Old High German knopf (“bud, pommel of a sword, knot, loop”), Middle High German knospe, German Knopf (“button, knob”), Knospe (“bud”), Danish knap (“button”), knop (“knob, button, bud”), Faroese knappur (“button”), Icelandic hnappur (“button”), Norn knapp (“round button”), knubbi (“potato”), snapp (“knob, round top”), Norwegian and Swedish knapp (“button”), Norwegian knopp (“bud”), Swedish knopp (“bud, knob”), Finnish nappi (“button, knob”), nuppi (“knob, pommel”), Old Norse knyfill (“short horn”). Also compare Middle English knap, knappe (“small projection, knob (button, tassel, tuft, etc.), hill, hilltop, etc.)”), from Old English cnæp, cnæpp (“summit, top”), which is possibly related to Old Norse knappr (“small projection, knob (button, head of a stick, etc.)”) (whence English knop), from Proto-Germanic *knappô (“knob, lump”), *knuppô (“lump, clod”).
