Student or Learner
I am a little confused about the differences between the following.
Every one of the students passed the test
Every student passed the test.
Each one of the students passed the test.
Each student passed the test.
I understand every one and each one requires a plural noun, but is there a difference between the singular and plural forms?
If you want to compare singular and plural, the past tense is not useful, since it's same in singular and plural:
The student passed - The students passed.
You need something like the present tense to show a difference:
The student passes - The students pass.
Adding a prepositional phrase "of the students" to a singular subject doesn't change its number:
Every one passes.
Every student passes.
Every one [of the students] passes.
Each one passes.
Each student passes.
Each [of the students] passes.
All students pass.
All [of the students] pass.
