Questions & Answers about כשהגשם נגמר, אפילו הסמטה הישנה ליד המזרקה נראית יפה יותר מתחת לשמיים הכחולים.
כש means when, and in Hebrew it is often attached directly to the following word as a prefix. So כשהגשם is literally when-the-rain.
What is happening here is:
כש + הגשם = כשהגשם
This is very normal in Hebrew. English keeps when separate, but Hebrew often joins short function words like this.
Hebrew often uses the definite article with natural phenomena more than English does. So הגשם literally means the rain, but in context it can simply mean rain in a general sense.
This is similar to how Hebrew may say השמש for the sun or השלג for snow in situations where English might be less definite.
So כשהגשם נגמר is a natural way to say when the rain stopped / ended.
