We often use neither with 'nor' ( formal) . E.g.

• Neither Caroline nor Marguerite works for El Corte Inglés.

• = Neither of them works for EL Corte Inglés.• Neither the boy nor the girls are coming.

• Be careful not to use neither with another negative e.g. I don’t want neither chocolate nor crisps.WRONG !• I want neither chocolate nor crisps. RIGHT We cannot have a double negative!

• Either is used with 'or' e.g. .

• Do you want either chocolate or crisps?• Either Tom or George must wash the dishes.• = Either of them/us must wash the dishes.• ‘Who’ll do it?’ ‘Either (of them).’
