Spelling & Dictionary Insight

The English entry for fail is 4 letters long, classified as averb, and transcribed in the International Phonetic Alphabet as /feɪl/. Corpus data places it at rank #2,441 in overall English word frequency, indicating it appears regularly in written and spoken text.Wiktionary records 15 distinct senses for this headword, so context determines which meaning a reader should apply.

Our Hunspell-derived misspelling index lists 5 documented wrong-spelling variants for fail, with forms such as "afil", "faill", and "fali". 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, "fi", "FL", "far", and more, where similar look or sound leads writers to substitute one word for another in context.

Etymologically, the entry records: Inherited from Middle English failen, borrowed from Old French falir, from Vulgar Latin *fallire, alteration of Latin fallere (“to deceive, disappoint”), from Proto-Indo-European *bʰāl- (“to lie, deceive”) or Proto-Indo-European *(s)gʷʰh₂el- (“to stumble”).… 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 fail, spelled F-A-I-L, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
