Sie und ich gehen
The Duolingo translation for it saids "you and i go" but i am wondering if there could be another one for example "she and i go" since the sie can be a she?
Also i have noticed this in many other phrases that sie can sometimes be used as you (not sure weather it's du or ihr) . So under what circumstances, case, or tense can sie be a she ?
When used in the nominative case, it could always mean she, they or you (pl.&sing. courtesy form). Decision help:
- Context (not given here; doesn't help here)
- Verb endings plural (--> they or courtesy forms of you) (it's plural here but for the reason that two people are involved --> this doesn't help you)
- Verb endings singular (--> she --> ain't singular here)
- Courtesy forms of you (i.e. Sie sing.&pl.) are always capitalized (doesn't help her since it's the beginning of the sentence anyway)
I come back to your question: Yes, she and I go is a feasible translation for sie und ich gehen, too, aswell is they and I go, you (sing. polite form) and I go and you (pl. polite you/y'all) and I go. You simply don't know without more context.
But since the capitalized Sie seems to be starting this .. let's loosely call it a sentence, it could be capitalized for simply that reason -- the starting position. Hence, while your statement is true, I hold that there is not enough context to completely rule out 'she' for a translation here.
