First of all, the upper cased 'Sie' is the formal you, rather than 'she'.
Second, 'sie' is the 3rd person singular female personal pronoun in nominative case. To say "her door", you would need the possessive 'ihr', which would be "ihre Tür" (inflicted properly since Tür is female).
Finally, you should read about the imperative mood in German - http://www.dartmouth.edu/~german/Grammatik/Imperative/Imperativ.html .
One of the possible ways to phrase an imperative in German is for the formal you - Sie - which was used here. You do that by using the infinitive form (e.g. essen, gehen, treffen, schließen. The exception to this is 'sein' which you will use 'seien' for) in the same structure as a question (i.e. verb first, then Sie.
For example "Eat it" would be "Essen Sie es"
Would it be correct to translate this more closely to "Please, can you close to door?" Or am I trying to hard to make the Sie work in my mind? Because in your other example of "Essen Sie es" would it not be able to be translated as "(You) Eat it" since the "you" in that sentence is implied in the command? Sorry for the possibly annoying question haha.
No worries. No, it cannot. The question you have in mind would be "Bitte, könnten Sie die Tür schließen?" -> "Please, could you close the door" (changed "can" which is for for inquiring about possibility, to "could" which is better for making a request/instruction).
Putting "please" aside, and like I said above, this is the same structure as the question "Are you closing the door?". You can tell the difference by the lack of question mark when written and the intonation when spoken, aside from context which usually would be enough.
Did I answer what you meant or was I off point?
Not necessarily, read about the imperative mood. German has a total of 5 imperative structures:
- 2nd person formal (Sie) - what you are referring to
- 2nd singular person informal (du)
- 2nd plural person informal (ihr)
- 1st person plural (wir)
- 3rd person (er/sie/es) - old fashioned, not really used
The pronouns are only included for Sie, wir, and third person but not for du and ihr.
No - What you suggested is not a valid imperative sentence in German (actually not a valid sentence at all). The closest is "Bitte die Tür schließen". Read about the imperative mood in German - http://www.dartmouth.edu/~german/Grammatik/Imperative/Imperativ.html .
Don't claim to be an expert but.... I think it is more common to say Machen Sie die Tuer zu! or informally Tuer zu! to request the door be closed. I hear zumachen much more than schliessen in use. Schliessen can also be used sometimes to mean to lock or closed. Sperren is also used for close or lock. Consider the road sign Strasse gesperrt! Good luck on figuring this one out!
If I'm not mistaken, that makes no sense. "They please close the door" would be a translation which you can see doesn't make sense. In this case (capitalised) it makes sense since using the format you Sie is also used as the imperative form (Close the door, or here - Please close the door)
So, in the dictionary https://dict.leo.org/german-english/Schlie%C3%9Fen I see that "schließen" can mean "to close" "to finish" or "to lock." How can one distinguish between a request to close the door versus one to lock the door?
