Classical Arithide adjectives

In Classical Arithide, adjectives were a rather nebulous class of words, and their indeterminate, halfway-house status contributed to their amorphism, or rather polymorphism, over the years, and indeed, a cursory glance at the adjectives in a certain text and the way they are inflected is one of the surest ways to discern the period from which it came.

In accordance with the language's left-branching nature, adjectives in Classical Arithide are generally placed before the noun they modify (as with adverbs and the relevant word they modify), but may technically be placed anywhere in a sentence due to the extensive case-marking system. This latter point is definitely true only for the standard dialect of the Equora dynasty; adjectival case-marking was rare before and gradually fell out of favour after the time, and even during the Equora, was adopted from an innovation of the dialects of western Calagia and Demedria.

Inflection

The Classical Arithide of the Equora dynasty, the most widely recognised variant and the common modern benchmark for "standard" Classical Arithide, had no adjectives per se: all words that could conceivably be used with an adjectival function were technically stative verbs, e.g. egnēn, "black", or literally, "to be black". The verb would then be conjugated egna to mean "it is black", or egne to express that it used to be black; this applied whether the adjective was used attributively ("the black car") or predicatively ("the car is black").

• Viringa egna. The sedan is black.
• Egna viringa dagemenum dakte. The black sedan stopped in front of the house. (lit. "is-black sedan house-front-at stopped")

In the nominative, generally no case endings are appended. When the adjective modifies a noun in a case other than the nominative, however, case endings become necessary for purposes of disambiguation, and the adjectival verb takes on the participle forms, namely egnāt- for egna, and egnēm- for egne.

• Viringa egna vage." The black sedan went.
• Viringetis egnātetis vage. (I/We/You/He/She/It/They) went in the black sedan. (lit. "by the black sedan")

The existence of the present- and past-state distinction enables some handy locutions as well:

• Ielane konkanditis egna assula levē agare The sky that was once blue but now black with rage howled ferociously (Oskes, Poetry)

Note: on occasion in attribution, the adjective may also be conjugated egni, to remove connotations of present or past states. Towards the end of the dynasty the innovation of using the present participle form (egnīm) grew popular, and subsequently gave rise to the -im adjectival ending of Modern Arithide.

Derivatives from verbs

The participle forms of verbs could also be used as adjectives, without much further modification, save the dropping of the final consonant. These derivative adjectives fall under the nominal class, and are not availed the subtle distinctions of present and past states as are the adjectives of the verbal class. Conjugation follows as per the declension class of the noun modified.

• Īde tath zurōnēs enēn mēsēs labi, futisi 'lārīē segē' nollos.
  

alas again cruel.PL return.INFIN Fate.PL call.PROG, hide.PROG-and.CLIT swimming.PL.ACC eye.PL.ACC sleep.NOM

"Alas again the cruel Fates are calling me back, and sleep is hiding my swimming eyes." ('Lēspēs, Laments)
