123: dumb Apr 10, 2015
Everyone now has an understanding of what 'dumb' means, be it 'stupid',
'socially inept' and/or 'dull', but this word did not always have such
connotations. The word 'dumb', came to English from the Gothic 'dumbs',
which meant 'mute'. Although this word still means "someone who cannot
speak", some dictionaries no longer include this definition, as it is
becoming archaic. Where the original sense of this word remains is in
the words 'dumbstruck' and 'dumbfound'.
