"Ayercomísopayunemparedado."

That is the current hot topic. :) The Europeans think it must be Mexican, those that know about Mexico say no, and it is not listed under "sandwich" in any of my dictionaries. I took a year of European Spanish, spent a month in Argentina, have been to Mexico and have Mexican friends, and I've never seen the word until Duo. brought it up.

I will go with some cultural insight first. No worries, it's for free

So, once upon a time, English was not the language for choice back in Spain and most of Latin America (Although I have less knowledge on Latin America culture) but French. In Spanish it was accepted to bring words from French, but not that well regarded from English.

The cultural facts between the old countries might also have some part, but I do not want to talk politics... the consequence (or at least one) is that many English words were translated or a new word was "invented" ad hoc for it.

More over, in Latin America, they used different "new" words for the translation or even chose to translate different words (this leads to puzzle faces on both sides of the Atlantic when discussing certain topics)

Now, another cultural insight is that, in Spain, the English loaf (besides being clearly heretic) was not commonly used. The Spanish loafs are similar to French (although there are many tasty varieties and some commercial crap you can't even smell, in the recent days). Actually, at least in Spanish, it's common to name the English loaf as "casted bread " (Pan de molde).

Therefore, there was nothing like the "Sandwich" in Spain. You have "breads" as they come from the different types of loafs and are generally called "bocadillo(s)" and might be filled with some tasty ham, tortilla (the Spanish one) or other stuff.

As you might see, the "Sandwich" was a totally different thing, that needed a new word.

In English you can use it as a verb, as in " I was sandwiched between two lorries and now I no longer have wing mirrors", meaning "to wall". To wall also refer to that practice of sealing somebody off between to walls.

And there we are. Emparedar is the literal translation of "to wall" and therefore Emparedado, "walled", the perfect word to describe some stuff between two slices of bread.

It is not used very often any more, at least in Spain, but... there you go.

I have seen it on menus in Tenerife, in the Canary Islands. It offers a distinct choice between those and bocadillos. If I just ask for a sandwich in english, I tend to get given a bocadillo. If I ask for an emparedado, I get something more like what I think of as a sandwich, made from two flat pieces of bread.

"Bocadillo" is the Spanish word.

If you're translating "we" to Spanish, either nosotros or nosotras should be accepted. If not, you should report it. If, in context, it's something like "we girls" or "us girls", than, yes, it's nosotras -- but I don't think DL gives us sentences like that.

If it's either nosotros or nosotras in Spanish, the translation is simply "we" in English. We do not distinguish between females and males in this case. (Same for "they". English only makes the distinction with he/she.)
