Learn Finnish: Minä ajan kotiin.

In Finnish, you change the ending of a noun to show direction. Doubling the last vowel and adding -n gives us kotiin, which means "to home." If you just said Minä ajan koti, it would sound like the home is the vehicle you are driving!

Does ajan mean "drive" or "am driving"?

It means both! Finnish doesn't have a separate verb form for an action happening right now. Minä ajan covers both "I drive" as a general habit and "I am driving" at this exact moment.

Is it okay to drop the word Minä and just say Ajan kotiin?

Yes, absolutely. Because the verb ajan ends in -n, it already tells us that "I" am doing the driving. Native speakers often drop minä in everyday conversation.

What is the dictionary form of the verb ajan?

The dictionary form is ajaa (to drive). To make it "I drive", you take the stem aja- and add the personal ending for "I", which is -n. This gives you ajan.
