Is the order of the following pronouns necessary?
1) You, he and I are of the same age.
2) We, you and they are in the same grade.

Is the order of the following pronouns necessary?
1) You, he and I are of the same age.
2) We, you and they are in the same grade.

What do you mean by "necessary"?

 

[jutfrank]

In 1, you need to put I last.

Just forget about sentence 2 and find another way to say it.

 

[GoesStation]

In 1, you need to put I last.

And he and you can go whichever way you prefer at the moment.

 

[Tdol]

Who is the you in the last sentence and how are they not part of we?

 

[Alice Chu]

Are there any rules for the order/sequence of personal pronouns?

 

[jutfrank]

Put I last.

I and you :cross:
you and I :tick:

I and she :cross:
she and I :tick:

Jutfrank has given you the only rule that applies to the order of pronouns (and even then it's not really a rule, more just a convention). All the others can be put in any order you like.
