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.[2] In 2010, it was named by the New York Times as one of its "Words of the Year".[8] American Dialect Society nominated Mansplaining as the “most creative” new word in 2012.[9]
