Usage

The correct spelling for the word meaning ‘diverse in character or content’ is heterogeneous, but a fairly common misspelling is heterogenous. The reason for the error probably relates to the pronunciation, which, in rapid speech, often skims over the fifth syllable as if to skip the e. Take care to note that heterogenous is a different word, which is used in specialized medical and biological senses and means ‘originating outside the organism.’

Origin

Early 17th century: from medieval Latin heterogeneus, from Greek heterogenēs, from heteros ‘other’ + genos ‘a kind’.
