We've seen a number of recent questions asking "Why is X in English different than Y in Spanish?" A couple recent examples:
I see two possible problems with such questions:
They assume that English and Spanish ought to be related in some way. While it's true that English and Spanish do have a number of similarities, in large part due to a shared Latin root, assuming that this root should yield similarities between any two given words with a similar meaning seems misguided.
These are really two questions, disguised as a single question. The two questions are "What is the etymology of X in English?" and "What is the etymology of Y in Spanish?" And only one of these two questions seems directly on-topic on this site. And the can be easily asked on EL&U.
Of course etymology questions may often be closed as too-simple, if the answer is easy enough to find, but that's a separate issue, I believe.
How do others feel?
We already have a related (but I think more broad) question in meta.
