The word "nor" is a conjunction used to connect two negative statements. It often appears in sentences where you want to express that neither one option nor another is true. For example, you might say, "I like neither apples fruit nor oranges fruit." In this case, "nor" helps clarify that both options are not preferred.
In addition to its use in negative statements, "nor" can also be found in more complex sentences. It can connect clauses that share a similar negative meaning. For instance, "She doesn't like running exercise, nor does she enjoy swimming activity." Here, "nor" emphasizes that both activities are unappealing to her.
