the meaning of the word "affected"

Hallo!!


I read a sentence yesterday when I was teaching my students a story written by the famous H.K.Anderson, "emperor's new clothes".

In the story, the two rougue come to cheat the king and claim that they know how ro weave invisible clothes. And then I found this sentence..

Both of them "affected to work" together .

What does this phrase mean? Is this archaic expression?

Thanks

It means that they pretended to work, but it also means that they made
a good show of pretending to work. Usually, affected is used as an
adjective (I write in an affected manner) but it can be used as shown.
