Neither Nor & Either Or




I haven't met my mother or my father (more common)- 

I have met neither my mother nor my father (more formal)- No he conocido ni a mi madre ni a mi padre

Neither my dad nor my mum smokes- Ni mi madre ni mi padre fuman


My dad doesn't smoke and my mum doesn't either-

My dad doesn't smoke, neither/nor does my mum- Mi padre no fuma, y mi madre tampoco


Either my mum or my dad has to attend the meeting- O mi madre o mi padre tienen que asistir a la reunión
