Every vs Each: Choose by Group Rule or One-by-One Focus
Do not translate both words as “all” and guess. Check whether the sentence covers the complete set or deliberately separates the members.

Every and each can be close in meaning, so there is not a universal rule that only one is possible in every sentence.
This page trains high-value decision signals. When ordinary English allows both words, the surrounding sentence decides which focus is intended.
Complete set or individual focus?
Same rule or condition across the whole set: every customer, every room, every department.
Members are deliberately separated: each candidate separately, each employee personally, each of the winners.
Every employee must attend the meeting.
The rule covers the complete set.
Each candidate will be interviewed separately.
The sentence deliberately separates the candidates.
Notice “of the”
One very useful signal is of the.
Each of the participants works.
Every of the participants does not. If you need every here, the wording is every one of the participants.
Signals worth noticing
Broad requirements and repeated conditions: must, required, has, applies to the complete set.
Separate treatment: personally, separately, in turn, each of the..., or a clear one-by-one action.
Words such as different or own can support individual focus, but they do not automatically make every impossible. Read the whole business picture.
Quick TOEIC check
Choose first. Then read the feedback and compare your decision with the signal in the sentence.
1. ___ customer must show ID before entering the building.
Correct. The sentence gives the same rule for the whole group of customers.
Not this time. Each of would need a different pattern, such as “each of the customers.”
Not this time. All would need a different pattern, such as “all customers.”
Not this time. Both is for two people or two things.
2. ___ of the participants was thanked personally by the manager.
Not this time. “Every of the participants” does not fit this pattern.
Correct. “Each of the participants” fits, and personally shows one-by-one focus.
Not this time. “All of the participants” would need were, not was, in this sentence.
Not this time. Both is for two, but the sentence does not give a two-person signal.
3. ___ room has a keycard lock.
Correct. The same condition applies to all rooms.
Not this time. Each of would need a different pattern, such as “each of the rooms.”
Not this time. All would need a different pattern, such as “all rooms.”
Not this time. Many means not all, so it changes the meaning.
4. ___ employee was given a different password.
Correct. Different password shows one-by-one focus.
Not this time. Every of does not fit this pattern.
Not this time. All would need a different pattern, such as “all employees.”
Not this time. Both is for two people or two things.
5. ___ of the two applicants submitted a different version of the form.
Not this time. Every does not fit before “of the two applicants.”
Correct. Each of the two applicants fits, and different version shows one-by-one focus.
Not this time. All does not fit this two-person individual-focus pattern.
Not this time. Many does not fit with “of the two applicants.”
A rushed-reading mistake
Fast readers may see two familiar words and choose from translation alone. That hides the signal that makes the item easier.
Weak choice
“They both mean all, so I will choose what sounds familiar.”
Better choice
“Complete set, one-by-one focus, or of the?”
Use repeated mistakes as evidence
A single missed item does not establish a Learning Block. If the same error appears repeatedly across several attempts, review whether you are translating too early, rushing past of the, relying on one remembered example, or continuing to debate after the sentence has already given you a useful signal.
You may choose before checking the wording around the blank.
You may rely on one familiar example instead of checking the current sentence.
You may reduce both words to the same translation and miss the focus.
You may keep debating after a clear signal has already narrowed the answer.
Use small TOEIC mistakes as a diagnostic
If the same every/each error keeps appearing in timed practice, review the decision pattern as well as the words. One missed item alone is not enough evidence to identify a Learning Block.
