+        *              Then result word is: word + hyphen + case ending.

+        * 2) Word consist of cyrillic letters.
+        * 2.1) Word is in plural.
+        *              Then result word is: word - last letter + case ending. Ending of allative case here is 'æм'.
+        *
+        * 2.2) Word is in singular.
+        * 2.2.1) Word ends on consonant.
+        *              Then result word is: word + case ending.
+        *
+        * 2.2.2) Word ends on vowel.
+        *              Then result word is: word + 'й' + case ending for cases != allative or comitative
+        *              and word + case ending for allative or comitative. Ending of allative case here is 'æ'.
