とわ

Japanese

Alternative spellings
永遠 永久 常

Etymology

/topa/ → /towa/

From Old Japanese. Appears in the Tales of Ise, likely dating to the early 900s CE. Pronounced as toba until the later Heian period.

Ultimate derivation unknown. May be a contraction of earlier 常 (tokotoba), or may have been an independent term used to form tokotoba as a compound.

Pronunciation

• (Tokyo) と​わ [tóꜜwà] (Atamadaka – [1])
• IPA^(key): [to̞ɰᵝa̠]

Adjective

とわ • (towa) ^{←とは (tofa)?}-na (adnominal とわな (towa na na), adverbial とわに (towa ni ni))

1. constant, permanent, everlasting

   Synonym: 常しえ (tokoshie)

Usage notes

Listed in some dictionaries as a 形容動詞 (keiyō dōshi, “-na adjective”); other sources only list this as a 副詞 (fukushi, “adverb”). Historical usage suggests that this was only used with particle に (ni) as an adverb, and not with particle な (na) or classical なる (naru) as an adjective. When this appears attributively, it is followed by particle の (no), the usual construction when using a noun to modify another noun.
