each, every的区别：each强调个体，every强调整体

The quantifiers each and every are a kind of determiner. They have similar but not always identical meanings. We always use them with a singular countable noun.

Each means "every one, regarded individually".

Every means "every one, regarded as a whole".

Sometimes, each and every have the same meaning:

• Prices go up each year.
• Prices go up every year.
  

But often they are not exactly the same.

Each expresses the idea of "one by one". It emphasizes individuality.

Every is half-way between each and all. It sees things or people as singular, but in a group or in general.

Consider the following example sentences:

• Every artist is sensitive.
• Each artist sees things differently.
• Every soldier saluted the president as he arrived.
• The president gave each soldier a medal.
  

each

Each can be followed by "of":

• The president spoke to each of the soldiers.
• He gave a medal to each of them.
  

every

Every cannot be used for two things. For two things, each can be used:

• He was carrying a suitcase in each hand.
• every
  

Every is used to say how often something happens:

• There is a plane to Bangkok every day.
• The bus leaves every hour.
  

Verbs with each and every are always conjugated in the singular:

• Each person is an individual. not Each person are an individual.
• Every animal needs food. not Every animal need food.
