Either/or and neither/nor are conjunctions used to connect two alternatives. Either is used with "or" to indicate one or the other possibility, while neither is used with "nor" to indicate that neither of the two possibilities are true. Some key rules for using these conjunctions include not using a double negative with neither/nor, and only using either with "or" and neither with "nor". Examples are provided to illustrate the proper usage.

2. Here are some rules to
remember when using
neither/nor or either/or.

Neither = can NOT be this
and also NOT that.
