Spelling & Dictionary Insight

The English entry for deep is 4 letters long, classified as anadj, and transcribed in the International Phonetic Alphabet as /diːp/. Corpus data places it at rank #945 in overall English word frequency, putting it firmly in the everyday core of the language.Wiktionary records 20 distinct senses for this headword, so context determines which meaning a reader should apply.

Our Hunspell-derived misspelling index lists 4 documented wrong-spelling variants for deep, with forms such as "ddeep", "deepp", and "depe". 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, "DP", "due", "die", and more, where similar look or sound leads writers to substitute one word for another in context.

Etymologically, the entry records: From Middle English depe, deep, dep, deop, from Old English dēop (“deep, profound; awful, mysterious; heinous; serious, solemn, earnest; extreme, great”), from Proto-West Germanic *deup, from Proto-Germanic *deupaz (“deep”), from Proto-Indo-European *dʰewbʰ… 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 deep, spelled D-E-E-P, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
