I think that was the definition I saw before. I don't know much about bull-fighting, as it is illegal in this part of Spain (the Canarias CA).

It's interesting that the Spanish Supreme court (perhaps influenced by the views of certain politicians on Catalonia) chose to rule that the Catalonia CA's ban on bull-fighting was invalid under the Spanish constitution although the Canarias CA and individual Ayuntamientos in the Galica CA and the Baleares CA can ban it without any complaint about breaching anything in the constitution. Also interesting that the parts of the Baleares CA that haven't banned it are the parts where it has never been practiced.

Hi Rosa,
I don't think any single English word will work for "duquetas" without an explanatory footnote, except in cases where the context makes it obvious what sort of thing is intended. So I'm leaving that as it was, except that that "p" in the footnote has to be a "c".
I'm annoyed with myself for mistaking "me encontré" for something diferent (pehaps "se me encontó") or perhaps for forgetting the meaning of encontrarse. I don't know why I got that wrong. Thanks for pointing it out.
She sings of his "ruedo of love" and her "dressed up plaza" and it seemed odd to use the same word for both "ruedo" and "plaza"; but "square" is just plain wrong, and I don't think using "plaza" in English would work because it means one of "shopping centre" (centro comercial), market place (plaza del mercado), or "square". So I guess it has to be "bullring" for both as that's clearly what "ruedo" is.
My translator's comment interpretation may well be wrong, as I said it's guesswork; I've added a little more explanation to it to try to make it clearer.

Actually, I've been trying to think of English words: one to cover the ring and bull-pens and stables (plus dressing rooms and offices and so on for matadors and assistants and staff) and the other to cover that the ring plus the area that holds the audience/spectators. I seem to recall knowing different words (or phrases perhaps) for space used by performers and staff and for space for the customers in several languages, but can't remember them in any language or even be sure which languages I knew them in (that's one of the problems with getting old).

Maybe I could use "ring" (for ruedo) and "bullring" (for plaza) as you suggest, but would "arena" (for "ruedo") and "bullring" work? I think that would sound better in English, and the difference is clearer in English - there would be no risk of someone thinking something like: "ring? what ring? oh, the bullring! why not say bullring?". "Arena" is used in the song, but I think in a way that would not clash with using it for "ruedo".

But I wouldn't use the word "sand", but the word "arena" - which in English has come to mean "place for competition or conflict or spectacluar display to take place" and can no longer (since about 1400 AD) mean "sand" although it was clearly taken directly from Latin.
