Questions & Answers about העיתון על הכיסא, אבל הספר על המיטה.
In Hebrew, the verb to be is usually not expressed in the present tense in simple sentences like this one.
So:
העיתון על הכיסא
literally: the newspaper on the chair
natural English: The newspaper is on the chair
And:
הספר על המיטה
literally: the book on the bed
natural English: The book is on the bed
This is completely normal Hebrew.
אבל means but.
It connects the two parts of the sentence:
- העיתון על הכיסא = the newspaper is on the chair
- אבל = but
- הספר על המיטה = the book is on the bed
So אבל works very much like English but.
