Questions & Answers about בלילה קשה לי להירדם כשיש הרבה רוח ורעש בחוץ.

Why does the sentence start with בלילה? Does that mean at night or in the night?

בלילה means at night / during the night.

It is made of:

• ב־ = in / at
• לילה = night

So literally it is in the night, but in natural English the best translation here is usually at night.

Putting בלילה first sets the time frame for the whole sentence: At night, it’s hard for me to fall asleep...

Hebrew often puts time expressions near the beginning of the sentence.

Why is it קשה לי instead of something more like אני מתקשה?

קשה לי is a very common Hebrew structure meaning it is hard for me.

Literally:

• קשה = hard / difficult
• לי = to me / for me

So קשה לי להירדם is literally something like It is hard for me to fall asleep.

This is a very natural Hebrew pattern:

• קשה לי להבין = It’s hard for me to understand
• קל לי לזכור = It’s easy for me to remember

You can say things with a verb like אני מתקשה..., but קשה לי... is extremely common and often sounds simpler and more natural in everyday speech.
