This research aims to focus on the changes that happen to a Hebraic word when
adding extensions.
We discovered that adding those extensions affects the rhythm changes, the voice
order changes, deleting and moving it, and sometimes return it to its
base, also adding the
extensions plays a role in changing the meaning.
We done all this work by comparing with the Arabic language, so the worth of this
work become greater, because the two languages belongs to the same language family.
This papers reports the investigation of extensions of the group by means of the cyclic group A=<a> of order p, where p is a prime number.
It has been concluded from this work that, all non isomorphic extensions of
the group C(n) by means of the group A ,that correspond to irreducible
representations of the group A , are: - p Z
