other是修饰可数名词复数的.而且它并不是剩下的全部.而others=other+名词的复数.如：There are many students on the playground.Some are walking.Some are playing basketball.Others（Other students）are talking.
而the other既可以修饰可数名词的单数,还可以修饰可数名词的复数.它表示两部分当中剩下的另外一部分的全部.
如：I have two pens.One is red,the other is grey.
再如：I have three pens.One is red,the others are grey.
而another一般来说有两种含义.一种表示三者以上当中的另外一个.另外的意思是表示“再,又”之义.
