How to say "old" in Japanese

Choosing the right word
  • 古いふるいJLPT N5approx.Common
    i-adjectiveThe everyday adjective for 'old' as said of things — buildings, objects, information — rather than of people; it can also carry a nuance of 'antiquated' or 'outdated'.
    ケンが使つかっている机つくえはもう古ふるい。↗
    The desk that Ken uses is old.
  • 旧きゅうJLPT N3approx.Common
    prefixMatches 'old' only in the sense of 'former' or 'ex-'; it is seldom the word you want for 'old' by itself, working like the prefix 'ex-' in compounds.
    Bureaucrats are testing the waters over revising old regulations.
  • 久しいひさしいJLPT N1approx.Common
    i-adjectiveNot a general word for 'old': it describes a long time that has passed, and covers 'old' only where English speaks of an old story, one that goes back a long way.
    驕おごる平家へいけは久ひさししからず。↗
    Pride will have a fall.
  • 中古ちゅうこJLPT N3approx.Common
    no-adjectiveFor 'old' it is really 'used' or 'second-hand': the word for pre-owned goods such as a used car or a used book, not a general way to say something is old.
    その中古ちゅうこの冷蔵庫れいぞうこはひどい代物しろものだった。↗
    That used refrigerator was a real dog.
  • 年取ったとしとったCommon
    prenominal modifierCovers 'old' of people — someone advanced in years, grown old. It is said of persons, not things: the word for 'old' when talking about a person's age.
    彼かれらは年とし取とった人ひとに大変たいへん親切しんせつです。↗
    They are kind to old people.

Use 「古い」 as the all-purpose adjective for old things, 「年取った」 for people advanced in years, 中古 for second-hand goods, 「久しい」 for a long passage of time or an old story, and 旧 for 'former, ex-'.
