Questions & Answers about קשה לקלוט את כל המידע.
Hebrew often does not use a dummy subject like English it in sentences such as It is hard....
So:
קשה לקלוט את כל המידע
literally feels more like
Hard to absorb all the information
In natural English, you need it, but in Hebrew you usually don’t.
Here קשה means hard or difficult.
In this sentence, it functions as the main predicate:
קשה לקלוט... = It is hard to absorb...
The word קשה can also mean harsh, severe, or hard in other contexts, but here the meaning is clearly difficult.
