In one of my posts (Are "passive participle" and " Passive voice" the same thing in Modern English?) I said
Are "passive participle" and " Passive voice" the same thing in Modern English?
The pattern used there is A and B are the same thing
.
Per one of my posts ("mean the same" vs. "mean the same thing"), "mean the same thing" is more preferred than "mean the same" and it is not just stylish thing. According to which, I guess "A and B are the same thing" is more preferred than "A and B are the same".
The question is which one of the following is more preferred? Is it just stylish thing? Are they interchangeable in any cases?
A and B are the same thing
A and B mean the same thing
