Description:
American English dictionary words for /usr/share/dict
This package provides the file /usr/share/dict/american-english-insane containing a list of English words with American spellings. This list can be used by spelling checkers, and by programs such as look(1). . This is an even larger list than the one installed by wamerican-huge, and possibly contains invalid words (as well as words that are very uncommon). Nothing prevents you installing both (and others) at the same time. . There are also -small and standard versions of this word list, and there are wbritish* and wcanadian* packages as well.
