i-adjective
desirable; wished for
Expresses that something is desired or hoped for; somewhat formal and less common in everyday speech than 望ましい.
平和な世界は誰にとっても願わしいことだ。
A peaceful world is something desirable for everyone.
Standard kanji spelling; the reading is ねがわしい.
望ましい is the common word for 'desirable' in modern Japanese. 願わしい is more formal and less frequent, often carrying a nuance of personal wish or hope.
Derived from the verb 願う (ねがう, 'to wish') + the adjectival suffix しい, forming an i-adjective meaning 'desirable' or 'wished for'.
