To put it, English is a "right-handed" language in regards to writing as they start from the left hand side of the page or margin while Hebrew or Arabic are "left-handed" languages since they start from the right hand side of the page or margin.

Eg. English books open from left to right - "right-handed" format

Eg. Arabic books open from right to left - "left-handed" format

Languages that support "left-handed" orientation in regards their writing:

In both cases, these languages can be formatted from right to left (complicit in the left-hand nature in relation to their text format), even countries that speak one of these languages have "left-handed" notebooks, i.e. there's a higher chance you'll find a "left-hand" notebook in Israel or the Middle East than in the USA or UK. Notebooks with vertical lines exist in Japan for example.

Since Hebrew & Arabic are "left-handed" format, as in from right to left as opposed to English or most European languages which are primarily aimed for "right-handed" folks since their notebook or text orientation is set from left to right. East Asian languages are flexible: either left to right (horizontally) like English but they can be read from right to left (vertically) as well.
