From the perspective of grammar, the female equivalent of son obviously is daughter.
But here's my question: It seems to be some kind of cliché that some people (Priests, wise men, or even real fathers) refer to young boys by "son" when speaking directly to them: e.g., "Son, you know that..."
Simply putting it in the correct female form "Daughter, you know that..." feels wrong, somehow. How would a person often calling young boys "son" call young girls?
What about - Again, we're talking about some kinds of stereotyped clichés here - a priest with an adopted daugther? I could definitely imagine him calling an adopted son son, while I don't know what such a person would call a daugther.
Asking because I am currently practicing my English by writing a small story.
