Corpus data places it at rank #15,005 in overall English word frequency, marking it as uncommon enough that many writers pause before typing it.Wiktionary records 2 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 moth, with forms such as "mmoth", "moht", and "mothh".

Etymologically, the entry records: From Middle English moth, moththe, motthe, moght, mohþe, mouȝte, from Old English moþþe, mohþe, mohþa (“any destructive insect larva”), from Proto-West Germanic *moþþō, *mottō, from Proto-Germanic *muþþô, *muttô (“moth, worm”), from Proto-Indo-European *mut… 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 moth, spelled M-O-T-H, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
