Adjectival noun

From Wikipedia, the free encyclopedia

An adjectival noun (Japanese: 形容動詞, keiyō-dōshi, "adjectival verb") or sometimes just adjectival is a noun that functions as an adjective. This term is often used in analyses of the Japanese language to refer to members of the word class commonly known as "na-adjectives".

There is one type of adjectival noun in modern usage, with inflections as follows.

Irrealis
未然形
Adverbial
連用形
Conclusive
終止形
Attributive
連体形
Hypothetical
仮定形
Imperative
命令形
-daro -daQ

  • The modern inflections are based on two primitive forms: d- and n-. The n- forms are historical older while the d- forms are newer and have replaced some of the older n- forms.
  • Irrealis -daro is found with particle -u, resulting in -darou (-darō). Historically it was -dara. /au/ reguarlly changed into [ō].
  • Adverbial -daQ is often found with past particle -ta, resulting in "daQta" -> "datta".
  • Adverbial -de is found before "aru" and "nai", as well as being used in 中止法.
  • Adverbial -ni is used in 連用修飾方.
  • Modern Japanese no longer inflects for imperative.

[edit] Etymology

The nar- and tar- forms share a common etymology. The nar- form is a contraction of case particle ni and r-irregular verb ar- "is, be": ni + ar- > nar-. The tar- form is a contraction of case particle to and r-irregular verb ar- "is, be": to + ar- > tar-. Both derive their conjugations from the verb ar-.

Both -dya and -da share a common etymology.
dya: ni te aru > de aru > dea > dya
da: ni te aru > de aru > dea > da

ni and te are particles and aru is the verb ar- "is, be". dya is prominent in the Kansai region, while da is prominent in the Kantō region. dya is written as "ja" in Hepburn-style romanization.
