lateral lisp khazi Hitler
Churchill succeeded as an orator despite being handicapped from childhood with a speech impediment. He had a lateral lisp and was unable to pronounce the letter s, verbalising it with a slur. He worked hard on his pronunciation by repeating phrases designed to cure his problem with the sibilant "s". He was ultimately successful and was eventually able to say: "My impediment is no hindrance". In time, he turned the impediment into an asset and could use it to great effect, as when he called Hitler a "Nar-zee" (rhymes with "khazi"; emphasis on the "z"), rather than a Nazi ("ts").
