British English dictionary for ispell (large)

 This package provides the british-large dictionary, based on the britishlrg+
 dictionary supplied with the source for ispell, with additional words added
 from the more comprehensive wbritish-large word list package.
 .
 This is larger dictionary than the one installed by ibritish. Nothing
 prevents you installing both (and others) at the same time.
 .
 There are also -small, -huge, -insane, and standard versions of this
 dictionary, and there are iamerican* packages as well.
 .
 The package also suggests wbritish-large because ispell's (L)ookup command
 needs a word list.
