The quality or state of being worthy of strong disapproval or regret; the degree to which something is lamentable.
From deplorable (from Latin deplorare, 'to weep over') + -ity (Latin suffix forming abstract nouns). The root deplore combines de- (thoroughly) + plorare (to weep), literally meaning 'to weep thoroughly over something bad.'
This word emerged from Latin's theatrical vocabulary—plorare originally referred to actors weeping on stage—so calling something 'deplorable' literally means treating it like a tragedy worthy of dramatic tears, which explains why the word carries such emotional weight.
