Mansplaining (a blend word of man and the informal form splaining of the gerund explaining) is a pejorative term meaning "(for a man) to comment on or explain something, to a woman, in a condescending, overconfident, and often inaccurate or oversimplified manner".[3][4][5][6]
In its original use, mansplaining differed from other forms of condescension in that it was said to be rooted in the assumption that a man is likely to be more knowledgeable than a woman.[7] However, it has come to be used more broadly, often applied when a man takes a condescending tone in an explanation to anyone, regardless of the age or gender of the intended recipients: a "man 'splaining" can be delivered to any audience.[4]
In 2013 Dictionary.com said it was adding both mansplain and the suffix (libfix) -splain to its dictionary.[8] Its announcement read in part: "In addition to being creative, this term, particularly the -splaining part, has proven to be incredibly robust and useful as a combining form in 2013." Mansplaining has also engendered parallel constructions such as womansplaining, whitesplaining, rightsplaining,[9] and goysplaining.[10]
As the word became more popular, several commentators complained that misappropriation had diluted its original meaning.[11] Joshua Sealy-Harrington and Tom McLaughlin wrote in the newspaper The Globe and Mail that the term has been used as an ad hominem to silence debate.[12]

The possibilities are seeming endless on the -splain front. This gives Dictionary.com reason to believe that -splain is not just a temporary fad, but rather a stable new addition to English along with its libfix cousins like -gate, -pocalypse, and -zilla.
Goysplaining is an outgrowth of people thinking that they know a lot about Judaism. […] The people who goysplain think that because they went to the trouble of reading an article, watching a documentary, or Googling something, they now understand an entire faith and should be congratulated for it.
But along the way, mansplaining has morphed from a useful descriptor of a real problem in contemporary gender dynamics to an increasingly vague catchall expression that seems to be inflaming the Internet gender wars more than clarifying them.
The use of terms such as 'mansplaining' (and its racial counterpart, 'whitesplaining') can cause disengagement. […] Without such engagement, these terms become unconstructive ad hominem attacks that sidestep meaningful debate when an opponent conveniently possesses privilege.
