The Letter Nun Kefufa is another letter which has a special letter which replaces it when it is used at the end of a word.
The Nun Kefufa should have a head like a Zayin, that is- a square head with 3 Tagin on it. Originally, Sofrim made the
Nun Kefufa with a long neck, so as to be able to put the top of the next letter near the head of the Nun Kefufa.
Nowadays, we arch the back of the right leg slanting downwards towards the right, to avoid any problems and to create
ample space. The base of the Nun Kefufa should extend beyond the end of the head. The total size of the Nun Kefufa
should therefore be 1 1/2 X3 kulmusim.
