Spelling & Dictionary Insight
The English entry for amphetamine is 11 letters long, classified as a noun, and transcribed in the International Phonetic Alphabet as /æmˈfɛt.ə.miːn/. Corpus data places it at rank #31,431 in overall English word frequency, marking it as uncommon enough that many writers pause before typing it. Wiktionary records 4 distinct senses for this headword, so context determines which meaning a reader should apply.
Our generated misspelling index lists 16 likely wrong-spelling variants for amphetamine, with forms such as "amhpetamine", "ammphetamine", and "ampehtamine". Each variant is a distinct typo pattern an edit-distance generator flags, typically a doubled-consonant error, a silent-letter drop, or a vowel substitution. It is not paired with a close-neighbour confusable in our dataset, which tends to mean the word is visually distinctive enough to stand on its own.
Etymologically, the entry records: Shortened form of a(lpha-)m(ethyl)ph(en)eth(yl)amine. 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 amphetamine, spelled A-M-P-H-E-T-A-M-I-N-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
