Mansplain

Have you heard of the word 'mansplain?' It's not the male version of menstruation, nor is it the name of a magazine. It's the word that describes a characteristic of men to want to explain something to someone all the time, especially to women. The first time I saw the word, I couldn't help but agree with the accuracy of the word pointed out. I think that it is a feature that characterizes men. Come to think of it, a lot of men that I know have a tendency to try to explain everything, without caring if the listeners are interested in what they are talking about. I'm naturally a listener rather than a speaker, so sometimes even I get annoyed by that kind of man.

Notes: 

Mansplaining has a very specific nuance of explaining things in a condescending manner.  It is not just explaining, but specifically explaining things in a way that assumes you are stupid.

"It's the word that describes a characteristic of men to want to explain something to someone all the time, especially to women"

I would write this sentence: "Mansplaining is the act, characteristic of men, of explaining things that they might not even know very much about, especially to women, in a condescending or patronizing fashion."  - but this sentence has so many comma splices, which is characteristic of my writing style.  

Your writing is getting better and better!  At this point, I am going to have to start editing your papers like I would a native speaker's.

Mansplain

Have you heard of the word 'mansplain?' It's not the male version of menstruation, nor the name of a magazine. It's the word that describes one of man's characteristics that tends to like tendencies to explain something to someone all the time, especially to women. The first time I saw the word, I couldn't help but agree with what the word pointed out. I knew that it was a feature that characterizes men. Come to think of it, a lot of men that I know have a tendency to try to explain everything, without caring if the listeners are interested in what they are talking about. I'm naturally a listener rather than a speaker, so sometimes even I get annoyed by that kind of man.

The word you are talking about is actually 'mansplain'.

Use the word 'male' to describe the quality of being a man. Similarly, you use 'female' to describe the quality of being a woman.

You need to use the singular form of man, because you are talking about the gender as a whole.

Use characteristic, instead of characteristics. When you make it plural, characteristic is a noun. You are using the word to describe the tendency, so it stays singular as an adjective.

Use 'tendencies' because a tendency is something that someone tends to do.

You are talking about one specific type of man, so the word needs to be singular rather than plural.
