If you are familiar with über ("above," "over," "across") and hinaus ("out," "afield"), the fact that über hinaus (also darüber hinaus) is often translated as "beyond" may not surprise you. Like in English, it can be used to talk about physical distance, or be used in a similar context to außerdem, which means "additionally" or "moreover."

Es ging über die Wiese hinaus in die große, weite Welt.

It went across the meadow, out into the big, wide world.

Although it may look similar, über hinweg cannot be used interchangeably with über hinaus. It is often translated with "over" or "through" and can be used to talk about time passing. Take a look:

Für Menschen sind Tiere oft treue Begleiter und helfen über so manche einsame Stunde hinweg.

Animals are often loyal companions for people, and help them through many a lonely hour.

As you can see, both of the examples above refer to time, and not to distance or extent. But in this next example, über hinaus very clearly means "over" and "away":

Eines Tages wird es so weit sein, und bis dahin träume ich mich über die Mauer hinweg zu dir.

One day it will be the case, and until then I will dream myself over the wall to you.

Go to Yabla German and make sure you understand how these phrases are used in a sentence. For each sentence you see, consider which other word could be used and what this says about the meaning of über hinaus or über hinweg in that particular context. 

A substantival possessive pronoun is a personal determiner that is used without an accompanying noun, such as "mine," "his" or "hers," "yours," "ours," and "theirs." In English, substantival possessive pronouns sometimes have a different form than standard personal pronouns with a noun: "my" becomes "mine," as in "My wallet is in my bag." "Oh, where is mine?" In German, however, the substantival variant depends upon the inflective ending of the original pronoun that it is replacing.

Ich nehme mal an, Ihre Schulzeit liegt ähnlich weit zurück wie meine.

I take it your time at school dates, likewise, back as far back as mine.

Since he is referring to his time at school (feminine noun, singular nominative case: die Schulzeit), the substantival possessive pronoun is inflected accordingly: meine. 
 

Dafür könnt' ich sie bei der Schulbehörde anzeigen,

I could report her for that to the school authorities,

aber dann stünde dein Wort gegen ihres.

but then it would be your word against hers.

Although the possessive of das Wort would be ihr Wort, the substantival possessive pronoun adds -es to the neuter singular nominative case. If the substantival possessive pronoun were standing in for a masculine noun, it would add -er for the masculine case. You will most often encounter -es endings on pronouns in the genitive case, so best keep a sharp eye out for this exception!
