Ordering multiple stress pronouns (other than moi)

Question

In the test, I was marked wrong on this question.

________ devez prendre une décision.

You and she need to make a decision.

☑️ Toi et elle

❌ Elle et toi

Elle et toi was marked incorrect, while Toi et elle was considered the correct answer.

However, according to the lesson, the only rule pertaining to the order of multiple stressed pronouns in the subject is that if moi is among them then it must be last. It uses Toi et moi as the example, but the text says moi should be last, not that toi should be first.

Am I overlooking something obvious, or is there a secret rule? I can’t believe that I am the first to encounter this, but I don’t see this exact issue discussed in the Q&A.

Thank you for clarifying,

Dusty

This is a really interesting question, Dusty, which I had to research as the rules are to do with stylistic convention rather than grammar.
The traditional rule of thumb taught in French schools is:
Toi et moi, lui et moi, toi et lui/elle…
More precisely, the order by person tends to be:
Priority                 Pronouns
2nd person            toi,vous
3rd person             lui, elle, eux, elles
1st person             moi, nous
 
So the natural order goes: 2nd → 3rd → 1st
 
Examples

Toi et elle  (not elle et toi)
Toi et moi  (not moi et toi)
Lui et moi  (not moi et lui)
Toi, lui et moi  (all three together)
Vous et eux

Hope this helps!
