1Easy; simple; not difficult — said of tasks, problems, books, language, etc. Pronounced やさしい, a homophone of 優しい ('kind/gentle') but a separate word with only the 'easy' meaning. The synonym 簡単 (かんたん) is also very common in everyday speech. In writing, the kanji form 易しい is the usual choice because the bare kana やさしい reads as 優しい by default. The kana spelling やさしい appears mainly in children's books or in specific contexts such as the 「やさしい日本語」 (Plain Japanese) initiative.
