In normal spoken language, you would say "pot" is a synonym for "kettle"; you would state the source first and then the target. But the page to create tag synonyms has the text-entry fields the other way 'round, and I caught myself filling it in wrong before submitting it - this time. This is the wrong order, IMHO.
There's plenty of whitespace, so it shouldn't be a problem to have the two fields next to each other instead. It would be even better with an "→" arrow in between, or perhaps something more verbal than just the two field headings.
