A simple regular expression to find plural endings in a string?

Question

Regular Expressions

Good afternoon! Please help me with a regular expression to find the presence of plural endings in the search string. I myself do not often encounter regular seasons, so I do not master them in skill. A quick google didn't turn up any results either. Here is the code:

Match suffix = Regex.Match(inputText.text,"[АЯ,ЫЕ,ЫЙ,ЬЯ]");
        if(suffix.Success){
          Debug.Log("множественное окончание:" + suffix.Value);
        }

The result returns matches if at least one of the available letters is present in the string. How to make it work not on individual char, but on their combination?
Thank you!

Answer 1

/(\S+(?:ая|ые|ый|ья))(?:\s|$)/i

Answer 2

RewriteEngine on
RewriteCond %{QUERY_STRING} ^uid.*?ru$ [NC]
RewriteRule ^icq\/validate\.html$ /index.php?

something like this, you can add a regular expression, I was too lazy to fully describe.
