Who Goes First?

I suspect that more than once in grade school you experienced a conversation something like this:

You: Hey! Me and Tommy want to go swing on the swings.

Teacher: Tommy and I.

This correction of two mistakes at once has led to the unfortunate habit, mostly in the better educated, of saying things like “…between Tom and I.”

We’ve been over the issue of case before. (Subjects use I and objects use me.)

But what about putting Tom first? If you followed that link, You saw that the end of the post makes passing reference to that question of why Tom goes first, but I want to go into it a little more now. (If you didn’t follow the link: I said that the reason for putting Tom first is humility, not grammar.)  That’s not quite the whole rule. The rest of the rule is:

Put the most important one first.

I see this exercised a lot in scientific writing. Suppose your team led the research, but others participated, too. Putting your team first makes sense because it fits the relationship. I ran into this recently in the March 2016 Scientific American, page 68, near the top of the first column:

We and other developmental biologists have spent the past few decades trying to understand how this cellular orientation system works.

The article is mainly about their team, but they want to give credit to others working in the same field. That’s okay. In fact, it’s humble to include the others at all.

Now you and Tommy can go play on the swing in peace!
