_A Crow-bar._--In Johnson's _Dictionary_ the explanation given of this word
is "piece of iron used as a lever to force open doors, as the Latins called
a hook _corvus_." In Walters' _English and Welsh Dictionary_, the first
part of which was published about the year 1770, this word is printed
"_Croe_-bar." Is it probable that the word _crow_ has been derived front
the Camb.-Brit. word _cro_, a curve? and that the name has been given from
the circumstance of one end of a crow-bar being curved for the purpose of
making it more efficient as lever?
