By what name are the twins now called in Chapter 4 of Lord of the Flies?
In the novel Lord of the Flies by William Golding, the author shows us a group of boys castaway on a tropical island. Some are older and dominant, like Jack and Ralph - others are younger and weaker like the twins. The main point about the twins is that they have no separate identity and so are treated as one entity by most of the other boys on the island. This even extends to their new name "Samneric." They could represent groups of people in society who act or vote as one mass, going over to one side or another 'en masse.' In this case, it is a choice between Ralph or Jack's gangs. Samneric make mistakes by going over, or being taken. to the side that hurts them, although both Piggy and Ralph try to help.
The names of the two twin boys are Sam and Eric. By the time we get to this chapter, people have stopped calling them by their individual names. Instead, they treat them as if they were one person. They have combined their names and now they just call them both Samneric.
The boys tend to call them this because they are twins (and therefore look alike) and because they always stick together -- they do everything together.
The twins are part of Ralph's group for most of the book, but then they go over to Jack out of fear (but still help Ralph out in Chapter 12).
