USAGE
There are two possible pronunciations of the word controversy： one puts the stress on the con- and the other puts it on the -trov-. The second pronunciation, though common, is still widely held to be incorrect in standard English.
词源
late Middle English: from Latin controversia, from controversus 'turned against, disputed', from contro- （variant of contra- 'against'） + versus, past participle of vertere 'to turn'.
