We are learning............................... English.

We write them this way because it is the English way.

Why do you use an umlaut?

Why do you have der, die and das, when most of the der items have no relation to anything masculine, and that goes for the die and das auch!

Just accept it folks. If you wish to speak English, that's the way it is. Klar?

In general, hyphens are used only when the composition of words is unclear otherwise. Search Google on using hyphens in compound adjectives.

Compound nouns are an exception to the above. A compound noun consisting of two nouns does not really need a hyphen for clarity's sake, and yet many compound nouns get one. This depends entirely on convention; various dictionaries may spell the same word attached, with a hyphen, and unattached. There is hardly any rule for this. The only logic in this is that, the older and more frequently used a word is, the more chance there is that it is written attached rather than unattached; hyphenated is somewhere in between.
