I've read that there are male and female words. Is that true?

This should be an easy one. Although I am old enough to dislike the current convention of blending male and female. Seamstress for example. Is a male called a seamstor? Actor and Actress is another. Just because the theater crowd wants to be asexual why should all of us join them? Kate Hepburn was an actress and Spencer Tracy an actor. The idea of blending words would have been a foreign concept to them. Go watch "Adam's Rib." How about "midwife?" Most of the world's languages have male and female nouns to this day. So yes there are male and female words.

Do you mean like in languages like French, German, etc., where words are classified as masculine, feminine, and neutral?
