Learn German: Im Frühling scheint die Sonne und es ist warm. - In spring the sun shines and it is warm.

In German, you almost always use the definite article (the) with seasons. All seasons are masculine (der Frühling, der Sommer, etc.). When you want to say "in the", you use the preposition in followed by the dative case dem. This combines into the short word im.

Are all seasons masculine like der Frühling?

Yes! All four seasons (der Frühling, der Sommer, der Herbst, der Winter) are masculine. This makes it easy to remember that you will always use im to say "in the" for any season.

Why does the verb scheint come before the subject die Sonne?

This is the V2 (verb-second) rule in action. Because the sentence starts with the time phrase Im Frühling (which takes up the first position), the verb scheint must take the second position. The subject die Sonne then has to move to the other side of the verb.

In the second part of the sentence, why doesn't the word order flip to ist es warm?
