Airman and I engaged in some discussion of a handwritten sign that I saw this afternoon. The sign says “Sorry, we’re out of Tomatoes!” (That’s verbatim.) I was so impressed with this burst of unexpected literacy that I took a picture of it and posted it to Facebook.
I, of course, know that the plural of “tomato” is “tomatoes”. Airman, on the other hand, feels that the plural of “tomato” can be “tomatos”. The OED, for what it’s worth, backs him up, but to me, that just looks wrong.
This is not a “who’s right” thing, because the OED does show “tomatos” as an alternate plural. This is more of a “How do most people do it?” thing.
