hi, could you tell me please which one is correct?
necessary omissions or additions?
or

Please supply the full sentence. At the moment, without context, both are possible, especially as you have a question mark.

This is the full paragraph :
“Intralingual” translation, manifesting itself in different types, is not limited only to the transmission of linguistic signs, it is also subject to cultural changes, omissions or additions necessary according to the social conditions of the target community.

“Intralingual” translation, manifesting itself in different types, is not limited only to the transmission of linguistic signs, it is also subject to cultural changes, omissions or additions necessary according to the social conditions of the target community.

In this context the wording is correct as written.

Note that you omitted cultural changes in your original question:
cultural changes, omissions or additions
They are all potentially necessary according to the social conditions...

That at least is my understanding of the sentence as it is written.

Thank you so much for your help Mr. Joe.
Could you explain please why the adjective comes after names while in English grammar the place of adjective is before the name?

I think there's a little bit of ellipsis going on here. The real meaning, without ellipsis, is:
...subject to cultural changes, omissions or additions [that are] necessary according to the social conditions...

Btw, in English those are nouns, not names (changes, omissions, additions):

I believe in French they may be called names (noms), and perhaps in other languages too.
