wbritish-small binary package in Ubuntu Bionic i386

 This package provides the file /usr/share/dict/british-english-small
 containing a list of English words with British spellings.
 This list can be used by spelling checkers, and by programs such
 as look(1).
 .
 This is a smaller list than the one installed by wbritish; nothing
 prevents you installing both (and others) at the same time.
 .
 There are also -large and -huge version of this word list,
 and there are wamerican* and wcanadian* packages as well.
