סֵפֶר
sefer
Everyday HebrewFormsסְפָרִים
MeaningA set of pages with words on them, all held together inside a cover.
HistoryThis word comes from a very old root that means "to count" or "to tell". In the Bible, thousands of years ago, a "sefer" was a written text, usually on a long roll of paper called a scroll. Over time, as people started making books with pages, the word came to mean the books we know today.
