限定词,顾名思义,是用来限定名词的一类词。我们知道,名词指代人、物、事、时、地、情感、概念等实体或抽象事物的词,但是在句子中,某一名词是特指,还是类指,是确定数量,还是不确定数量,这些都要靠“限定词”来决定。

因此,限定词是在名词词组中对名词中心词起特指、类指以及表示确定数量和非确定数量等限定作用的词类。

英语的限定词有以下几类:

1.冠词:定冠词、不定冠词、零冠词

The red book is mine.

There is a pen and  an apple on the desk.   

Time is money.

2.物主限定词:my, your, his, her, our, your, their, one's, its. 

My bike is broken.

3.名词属格:John's, my friend's.
