Interslavic adjectives are formed by adding endings (and sometimes also prefixes) to other words. They are inflected and have three genders in singular (plural is only one for all genders). Words are palatalized during adding these endings (e.g. k→č, h→š, g→ž). Adjectives ending at č,š,ž,j have soft pattern (e.g. svěži, svěžego), otherwise have hard pattern (e.g. dobry, dobrogo).

The most used endings (in the order m. f. n. pl.) are:

• -sky, -ska, -sko, -ski. This is the most used ending aimed for general use.
  
  example: Rus, russky = Russian (noun), Russian (adj.)
  
  
  
• -ji, -ja, -je, -ji. This expresses some origin, in the way of meaning "ot + genitive" = "from somebody/something".
  
  example: bog, božji = God (noun), god, divine (adj.), něčto ot Boga jest božje = something from the God is divine.
  
  
  
• -ov, -ova, -ovo, -ovi. This expresses some kind of an ownership by a masculine subject, in the way of meaning "genitive" = "of somebody/something".
  
  example: petrova kniga = Peter's book, book of Peter.
  
  
  
• -in, -ina, -ino, -ini. This expresses some kind of an ownership by a feminine subject, in the way of meaning "genitive" = "of somebody/something".
  
  example: anina kniga = Anna's book, book of Anna.
  
  
  
• -ny, -na, -no, -ni. This expresses some source, in the way of meaning "iz + genitive" = "from somebody/something".
  
  example: železo, železny = iron (noun), iron (adj.), něčto iz železa jest železno = something from iron is from iron.
  
  
  
• bez- -ny, bez- -na, bez- -ne, bez- -ni. This expresses some exclusion, in the way of meaning "bez + genitive" = "without somebody/something".
  
  example: meso, bezmesny = meat (noun), without meat (adj.), něčto bez mesa jest bezmesno = something without meat is without meat.
  
  
  
• nad- -ny, nad- -na, nad- -ne, nad- -ni. This expresses some augmentation or elevation, in the way of meaning "nad + instrumental" = "above/super somebody/something".
  
  example: zemja, nadzemny = earth (noun), aerial, superterrestrial (adj.), něšto nad zemjej jest nadzemno = something above the Earth is aerial.
  

Of course, these endings can be combined as for example: petrovska orchestra (-ov + -ska) etc.

gradation

Adjectives have the same system of gradation as in English in three stages: indicative, comparative and superlative. Moreover in addition, there is the augmentative as the possibility to amplify the property in indicative.

1. indicative
   This is the standard form of an adjective.
   
   examples:
   zeleny = green;
   gluboky = deep;
   dragy = dear;
   svěži = fresh.
   
   
   
2. comparative
   This the higher level of property made by endings -ějši, -ějša, -ějše, -ějši or -ejši, -ejša, -ejše, -ejši after palatalized consonants č, š, ž. When comparing, the genitive case and the preposition ot = from is used.
   
   examples:
   zelenějši = greener;
   glubočejši = deeper;
   dražejši = dearer;
   svěžejši ot togo = fresher (more fresh) than this.
   
   
   
3. superlative
   This the absolute level of property made by prefix naj- added to the comparative form. When comparing, the genitive case and the preposition iz = from is used.
   
   example:
   najdražejši iz vsih ljudij = the most dear/valuable from all people.
   
   
   
4. augmentative
   This is the augmented form of the indicative made by prefix naj- added to the indicative form. It is used for example in a respectful salutation.
   
   example:
   najdragy gospodi! = (very) dear Sir!
   

descriptive gradation

Like in English we can also use descriptive gradation. Unlike English, however, the basic form of gradation is applicable to all kinds of adjectives. This descriptive gradation is made by adding adverbs vyše, najvyše (higher, the highest) or bolje, najbolje (bigger, the biggest). Both have exactly the same meaning as "more, the most" in English. The augmentative can be expressed using the adverb mnogo (much, many, a lot of, plenty of).

example:

1. dragy
2. dražejši = vyše dragy = bolje dragy
3. najdražejši = najvyše dragy = najbolje dragy
4. najdragy = mnogo dragy
   

irregular gradation

Although Neoslavonic is an artificial language, it can not exist without irregular adjectives. They are present in all Slavic languages. The Neoslavonic has only five of them:
