The Anglicized pronunciation with stress on the first syllable, (ăk′yə-mən), was accepted as standard by the entire Usage Panel in the 1997 survey and was the preferred pronunciation of two thirds of the Panelists. The older pronunciation was considered unacceptable by 40 percent of the Panel, suggesting that eventually this pronunciation will fall into disuse.
