Reason: Yesterday, I finally found the tag distinguishing swimming_fins (finlike accessories worn on the feet, legs or hands) from flippers (broad, flattened limb adapted for aquatic locomotion ). I'm from a region/grew up with the term "flipper" as commonplace (similar to how sucker aliases to lollipop), so it was a source of confusion for me. Here's a pair of aliases to redirect between the two uses, plus more to synonyms for swimming_fins. It has quite a few already, having seven aliases.
