This is a list of common misspellings. Please note that Memory Alpha uses American spellings exclusively. Most of the words on this list are not actually misspellings but rather the British version of the word. The misspelling is the first word, with the correct spelling contained in brackets afterward. Note that British spellings of words in place names, titles etc. are to be retained if that's how they were originally spelled.
