The American English dictionary Merriam-Webster recently added a lot of new words to its online site . Learning English reporter Bryan Lynn looked into the changes . He's joined me in the studio to talk about some of the new words . First off , how often does Merriam Webster add words ? Is this a yearly event ? No , actually it's not . The last time the company added new words online was 2014 . But an editor at large , Peter Solokowski , said Merriam Webster had been “watching ” some of the added words for many , many years . Others , he said , were much newer in use . I mean the new terms cover areas including science , technology , sports , pop culture . Most will probably be familiar to you . So , for example … That means to watch many episodes of a series in a short period of time . To binge , in this case , means to do a lot of something in a short amount of time . Right…so in this case , I guess , watching one after the other for a few hours straight . Some people might watch a whole season of a show over a few days . So here's another from the list you collected : Seussian . Some Learning English fans outside America might not know this one . Yeah , so Seussian is an adjective that refers to the American children's book writer known as Dr . Seuss . He wrote these fantastical books for young children that included fun rhymes and colorful pictures . The books made you laugh but they also helped a lot of kids learn to read . So anything that reminds a person of a Dr . Seuss world could be Seussian . "Green Eggs and Ham " was the first book I ever read , actually . Another one on your list is photobomb . That's when someone jumps in front of a camera uninvited . It's usually done as a joke . I've seen some pretty funny photos that were the result of a really good photobomb ! But , you know , it's not meant "to throw shade on anyone ." Oh , so I guess that is another newly added phrase , to throw shade ? Yes , it is . So , it is a slang expression that means to publicly express disrespect or dislike for someone . But to “throw shade ” the insult or offense has to be subtle or understated . So , among the new words are slang expressions , as well ... So , one of those is ghost . We all know what that means as a noun , but ... Right , but as a verb it means to abruptly cut off contact . I have friends who have been quite hurt by people who have just ghosted on them , without any explanation . It's not a very nice thing to do . Right , so I mean , with the slang words you could even pile on top , right ? You could throw shade and also ghost the same person . Oh...Okay , so here is another word on this list : microaggression . So is ghosting an example of microaggression ? Well , microaggression is a noun . It's a comment or action that subtly and often unconsciously or unintentionally expresses a prejudiced attitude toward a member of a minority group . Okay , so that sounds a little more serious than "ghosting ." Alright , so this next word is not slang and I'm not really sure most people know what this one means : prosopagnosia . Yes , so this is a noun and it does have a scientific meaning -- the inability to recognize faces . Exactly , that's what it would be . Blind to faces . Well , this has been really interesting , Bryan . Thanks for joining me in studio here . And to our listeners , let us know if you liked this and maybe we can do more of this in the future .
