Learn Danish: Ja, jeg taler dansk. - Yes, I speak Danish.

To turn a statement into a yes/no question in Danish, you move the verb to the front. So instead of starting with the subject like in jeg taler (I speak), you start with the verb to ask taler du dansk?. Danish doesn't use a helper word like 'do' to form questions the way English does.

Why is dansk written with a lowercase letter?

In English, we always capitalize languages and nationalities. In Danish, languages like dansk, nationalities, and days of the week are written with lowercase letters unless they are the very first word of a sentence.

I have also seen the word jo for 'yes'. Why are we using ja here?

You use ja to answer a regular, positive question. You only use jo when you are saying 'yes' to contradict a negative question or statement. For example, if someone asked 'Don't you speak Danish?' and you wanted to say that you actually do, you would answer with jo.

Does taler mean 'speak' or 'am speaking'?

It means both! Danish doesn't have a separate 'am doing' tense. So jeg taler translates to both 'I speak' and 'I am speaking' depending on the situation.
