1. Each:
Use "each" when you are talking about individual items in a group, emphasizing them one by one.
- Example: "Each student received a book."
- Condition: "Each" is used with singular nouns, even when referring to multiple items.
2. Every:
"Every" is similar to "each," but it emphasizes the whole group.
- Example: "Every student in this class passed the exam."
- Condition: "Every" is used with singular nouns, but it implies all group members.
3. All:
Use "all" when you are talking about the total number of people or things in a group, treating them as a whole.
- Example: "All students passed the exam."
- Condition: "All" is used with plural nouns and uncountable nouns (e.g., "all the water," "all the people").
4. Both:
Use "both" when you refer to two items or people together.
- Example: "Both teachers are helpful."
- Condition: "Both" is used with plural nouns, specifically referring to two items or people.
Pay Attention:
We can use "of" after "each" when referring to individual items or people in a specific group, but not after "every."
Example with "each of": Each of the students has a pencil.
Example with "every": Every student has a pencil. (No "of" after "every.")
