Both vs Either vs Neither

1) Both
     - the two alternatives ( 2 alternatif)
     Eg: I can speak both English and Spanish

2) Either
     - one of the two alternatives ( 1 daripada 2 alternatif)
     - this OR that ( ini ATAU itu)
     Eg: I can speak either English or Spanish. Which is easier for you to understand.

3) Neither
    - none
    - not this AND none the other (bukan kedua-duanya)
    Eg: I can speak neither English or Spanish
