"El espejo sigue aquí."
Sigue means follow, according to the definition when I click on sigue. Confusing.
This was a tough one but after researching dictionaries, idioms and common use I did find several examples of sigue being 'remains'. How it was explained was that sigue in this context means 'it continues to be'. Someone pulled this one out of a deep cavern however.
It is very confusing, because the verb "seguir" means just to follow. Normally the sentence must be "El espejo sigue estando aquí.", as seguir + verb in the present participle means to continue to do something. Please correct me if I'm wrong.
Maybe this is supposed to be stating a command, such as to say that the mirror is not to be taken from its' place. If so, I suppose it doesn't require the helper verb, huh?
Ah yes, this makes sense, I think you're right. "The mirror continues here" being the dictionary translation. Seems like queda would still make more sense though.
I wonder why queda wouldn't be used here. I don't see "remains" or "stays" listed anywhere as a translation of sigue.
When pasting this into Google Translate, it gives "The mirror still here." It seems to translate "sigue aquí" to "still here" as a unit. It seems though, that if that were a correct translation, we would need a helper verb, a la "el espejo está sigue aquí."
When putting "The mirror is still here" or "The mirror remains here" into GT, both give this phrase as a correct translation. "is still here" or "remains here" both produce "sigue aquí" as options.
However, "sigue" can mean "continues" or "still" so it appears that's how it's being used here: "The mirror continues [to be] here" or "The mirror [is] still here." I'm still not sure why either ser or estar is not needed though.
I talked to my sister (fluent) and her husband (native) and they say the best way to say this would be "el espojo se queda aquí." Neither seems to be sure whether duolingo's translation is acceptable. They did say that using estar in the phrase "sigue estar aquí" would not work though. Either this is wrong, or it's just one of those cases where two words mean something different together than each means alone.
