Word 396: ו־ (ul)

Why a hyphen? Because of the strangeness of next word, B.

Whenever a Hebrew letter is to be put at the head of a word written in non-Hebrew letters a hyphen is used. Look at word number 314.

No matter that this word consists of one, two, three or more... letters: a hyphen has to be written between the non-Hebrew letters and the Hebrew one/s so that the distinction be made quite clear.
