The older pronunciation gives this word two syllables, with a slight stress on the first: â€˜conned itâ€™ ï€¯ï€¢ï«ï‘ï®ï¤ï‰ï´ï€¯. (This pronunciation can still be heard in academic circles). The newer habit is to give the word three syllables â€˜conned oo itâ€™, with fairly even stress: ï€¯ï«ï‘ï®ï¤ïµï‰ï´ï€¯. (This pronunciation can also be heard in academic circles.)
Jones (1992) gives three major pronunciations: ï€¯ï€¢ï«ï‘ï®ï¤ï‰ï´ï€¯ [old-fashioned ï€¯ï€¢ï«ï–ï®ï¤ï‰ï´ï€¯, as electrical term also ï€¯ï€¢ï«ï‘ï®ï¤ïªï•ï‰ï´ï€¯ and ï€¯ï€¢ï«ï‘ï®ï¤ï·ï‰ï´ï€¯]. OED only records two syllables, albeit with two versions, having different vowels: ï€¯ï€¢ï«ï–ï®ï¤ï‰ï´, ï€¢ï«ï‘ï®ï¤ï‰ï´ï€¯.
The variation in pronunciation, even in the educated community, is a further illustration that a Guide such as, this which aims to help you use the language better, is doomed to failure. â€˜Goodâ€™ English is often a matter of taste in choosing between different permitted options.
