All Every Each English Grammar [Quyidagi ma’lumotlar internet saytidan ko’chirma qilindi] The difference between

Each of the guides has a different group to show around the museum.

Notice how after each of the verb is usually in singular form though when speaking informally, you will sometimes hear a plural verb used.

• 
  Each of my students has a different assignment to complete. (correct use)
  
• 
  Each of my students have a different assignment to complete. (informal use)
  

Each of + pronoun (you/us/them)

We can only use the pronouns you/us/them after each of.

• 
  He gave each of us a small gift at the end of the course.
  
• 
  You need to wash each of them before use.
  
• 
  Each of you needs to complete the assignment individually.
  

Again the verb following each of + pronoun should be in the singular form.

Each as a pronoun

Each can be used by itself (without a noun) as a pronoun.

• 
  When the students finished to course, each was given a certificate. (Each = each of the students)
  

Though it is more common to use each one instead of each by itself.

• 
  …each one was given a certificate.
