After reading an article in which it was stated that Che Guevara became a confidante of Fidel Castro, I am now very confused about the proper usage of the words confidante and confidant.
Every definition I can find of "confidante" says that it is mainly used for a female friend with whom you share personal information. This obviously doesn't work in the case of Fidel Castro and Che Guevara. In addition, I have read or heard this word used many times to refer generally to a friend with whom you disclose personal information - male or female. Actually, I always associated this word with a male friend...
The dictionaries say that "confidant" is the term used for a male friend in this regards, but I rarely even see it used.
So my question is, has the usage of "confidante" become more gender-neutral in recent history or am I just ignorant? Is it appropriate to use "confidante" to refer to a male friend, or should I only use "confidant"?
