Alphabet is the word
I am a word of three syllables, such that when you take away 5 letters, a male remains; if you take away 4 letters a female remains; if you take away 3 letters, a great man will appear; and the entire word shows you what Joan of Arc was. Do you know me?
Eliminate all 26 letters of the alphabet in alphabetical order, but not necessarily starting with 'A', to reveal a sentence.
