Speak like a native with A Dictionary of Japanese Idioms. Find the best expression for every situation!

What student of Japanese has not grappled with the amazing diversity and tantalizingly elusive nuances of its idioms? One certainly would not want to confuse, for example, ki ga mawaru (to be considerate) with ki o mawasu (to be suspicious). And it would be useful to know whether your boss is hara ga tatsu (angry) or merely ki ga tatsu (upset). Indeed, even a single idiom can have a bewildering number of meanings depending on context: te o ireru, for instance, can mean tidying up (e.g. a room), sounding out someone, or staging a raid.

This dictionary offers the most comprehensive compilation and English translation of those idiomatic expressions that so enrich the Japanese language but fail to find their way into conventional dictionaries. It presents 10,000 idiomatic phrases under some 2,200 main entries, including several thousands of idioms never presented and explained in English before. Multiple sample phrases are given for each entry, and furigana (as well as Internet audio) allows even beginning students to correctly pronounce and use the expressions immediately.

FEATURES include:
- Search-as-you-type in English and Japanese
- Spell-checking in English and romaji
- Bookmark, annotate and share entries
- Jump to other apps and web dictionaries
- Portrait & landscape modes
- Split view/slide over multitasking
- Night mode (dark mode)
- Spotlight search
- Today Widget
- Optional high-quality audio

Based on “A Dictionary of Japanese Idioms” by William de Lange, Floating World Editions.
