Learn German: Wir fahren Ski.

English uses "are skiing" to show an action happening right now. German doesn't have this continuous form. Instead, you just use the regular present tense. So Wir fahren Ski translates to both "We ski" and "We are skiing".

Why is the word Ski capitalized?

In German, all nouns (words for people, places, and things) are always capitalized. While "ski" is often a verb in English, German treats it as a noun in this phrase. The literal translation is closer to "We drive skis".

How is the word Ski pronounced?

Even though it is spelled exactly like the English word, it is pronounced like "shee" in German. This is because the word was originally borrowed from Norwegian.

If I wanted to ask "Where are we skiing to?", would I use wo, woher, or wohin?

You would use wohin to ask about the destination of your movement ("Where to?"). The question would be Wohin fahren wir Ski?. If you just wanted to ask about the general area where you are skiing without focusing on moving to a new destination, you would use the locational word wo.
