Incorrect spelling, explanation: a lot of spelling mistakes in English appear when the -able suffix is added to a word. The spelling of the word usually changes then, but a number of English speakers tend to forget about that. Such a thing happens, for example, in the case of undecidable, which is often misspelled as
undecideable. The -e letter at the end of the root word – decide – disappears, when the -able ending is added.
