Learn Danish: Jeg er her.

No! Danish verbs are incredibly friendly. The verb er means "am", "are", and "is". It stays exactly the same no matter who the subject is, so you will say jeg er (I am), du er (you are), and han er (he is).

How is the word jeg pronounced? It doesn't look like it sounds.

In Danish, the letter j makes a "y" sound, and the g in this word is silent. So jeg is pronounced somewhat like the English word "yay" or "yigh".

I'm having trouble hearing the "r" in er and her. Is it silent?

Danish "r"s at the end of words or syllables are usually vocalized, meaning they sound more like an "ah" vowel than a crisp English "r". So er sounds a bit like "ah", and her sounds like "hah" or "hair" without a hard consonant at the end.

Does her mean "here" in all situations?

In this sentence, her is a locative adverb, which means it describes being stationary in a location. You use it when you are already somewhere. If you were talking about movement towards a place (like "I am coming here"), Danish often uses a different word, like herhen.
