Beyond the definition
Defamation is the legal system's recognition that words can wound as surely as blows — and that the wound to reputation can be harder to heal than the wound to flesh.
Origin & history
From Latin 'defamatio' (taking away of fame); from 'defamare' (to spread harmful report about); from 'de-' (taking away) + 'fama' (reputation).
