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 when the adjective was predicative ("the car is black"). When the adjective is used attributively ("the black car"), the progressive tense is employed for current states egni, but past states still retain the past tense of egne.

• Viringa egna. The sedan is black.
• Egni 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 form in the past tense, namely egnēm- for egne, but simply adds endings to the progressive tense.

• Viringa egni vage." The black sedan went.
• Viringetis egnitis 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 egni assula levē agare The sky that was once blue but now black with rage howled ferociously (Osces, Poetry)

Note: towards the end of the dynasty the innovation of universally using prenominally 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.
