Questions & Answers about אני מקווה שכאב הראש יעבור עד מחר בבוקר.

What does ש mean in שכאב הראש יעבור, and why is it attached to the next word?

ש is a very common Hebrew connector meaning that.

So:

• אני מקווה = I hope
• שכאב הראש יעבור = that the headache will go away

In Hebrew, ש is usually written as a prefix, attached directly to the following word. So שכאב is really:

• ש + כאב

This is completely normal in Hebrew spelling.

Why is כאב הראש used for the headache? Is it literally pain of the head?

Yes. Literally, כאב הראש is something like the pain of the head.

Hebrew often expresses this kind of idea with a construct phrase (called smikhut), where two nouns are linked:

• כאב ראש = headache / a headache
• כאב הראש = the headache

So English uses one word, headache, but Hebrew often builds it from two nouns: pain + head.

Why is the ה only on הראש and not on כאב?
