"eure" is "yours" for plural "you". All the pronouns you can find here: http://en.wikibooks.org/wiki/German/Grammar/Pronouns
I just found this out, turns out "Eure" is the informal version of "Ihre". The table should be of great help. http://blogs.transparent.com/german/mein-dein-sein-ihr-etc-german-possessive-pronouns-in-the-nominative-case/
In the link above, you may have noticed that the plural of mein(e) is unser(e), which is completely different because these have nothing to do with each other (like my and our in English), and I suggest you seperate the two in your mind otherwise you'll confuse yourself with "two layers of plural".
For the individual possessive pronouns, the plural is just plural, and there's no gender as I said:
- euer Mann (singular masculine)
- euer Kind (singular neuter)
- eure Frau (singular feminine)
- eure Männer/Kinder/Frauen (plural)
Yes, at the beginning of the sentence, capitalized "Ihre" can mean Your, Her or Their:
- Ihre Männer sind stark. = Your men are strong. (2nd person, singular, formal)
- Ihre Männer sind stark. = Her men are strong. (3rd person, singular, feminine)
- Eure Männer sind stark. = Your men are strong. (2nd person plural, colloquial)
- Ihre Männer sind stark. = Their men are strong. (3rd person plural)
As you can see above, georgetan linked a very useful table which will help you for sure: http://blogs.transparent.com/german/mein-dein-sein-ihr-etc-german-possessive-pronouns-in-the-nominative-case/
"Eure" is for plural "your" before feminine gender and plural words (regardless the gender of them), "dein" is for singular "your" before masculine and neutral gender words.
Yes, deine is used with nouns in feminine or plural form (which would use article die), if a single person possesses them and you're addressing this person (2nd person, singular) in an informal way (friendly relationship).
- Ich mag deine Schuhe. = I like your shoes. (plural)
- Ich habe deine Jacke gefunden. = I have found your jacket. (feminine)
- der Schuh = the shoe
- die Schuhe = the shoes
- die Jacke = the jacket
It's dependent on the following noun's gender and singular/plural statue. Basically, masculine or neuter gender noun requires mein/dein, feminine or plural (regardless the gender) noun requires deine/meine. http://en.wiktionary.org/wiki/dein. What is more important is, it's not enough to learn the language with Duolingo only, a dictionary with grammar section (or simply google it) would be necessary here.
Der Mann is masculine, so "Your man is strong." would be:
- Euer Mann ist stark.
- Dein Mann ist stark.
Die Frau is feminine so "Your woman is strong." would be:
- Eure Frau ist stark.
- Deine Frau ist stark.
Das Kind is neuter, so "Your child is strong" would be:
- Euer Kind ist stark.
- Dein Kind ist stark.
