Learn Icelandic: Nei, ég er læknir.

Icelandic does not have a word for "a" or "an" (this is called an indefinite article). To say "I am a doctor," you simply say ég er læknir, which literally means "I am doctor."

The verb here is er (am). Is this the same word used for "is"?

Yes! The verb vera (to be) is exactly the same for "I" and "he/she/it". You use er to say ég er (I am), hann er (he is), hún er (she is), and það er (it is).

How do you say "you are a doctor" based on this lesson?

For "you" (singular), the verb changes slightly. Instead of er, you use ert. So, "you are a doctor" becomes þú ert læknir.

Does the comma after Nei change the order of the other words?

No. Words like Nei (No) and Já (Yes) sit outside the main sentence structure. The actual sentence starts with the subject ég, followed by the verb er in its normal second position.
