How to say "shorten" in Japanese

Choosing the right word
  • 縮めるちぢめるJLPT N2approx.Common
    ichidan verb, transitive verbThe general transitive choice: you make something shorter or smaller — a distance, a span of time, a piece of writing. Its gloss also covers 'reduce' and 'condense'.
  • 縮まるちぢまるJLPT N1approx.Common
    godan verb, intransitive verbThe intransitive counterpart of 縮める: something becomes shorter, or a gap narrows, without an agent being stated — distances, differences and spans of time shrink.
  • 略すりゃくすJLPT N2approx.Common
    godan verb, transitive verbFor shortening by omission: abbreviating a long word or name, or abridging a text. When 'shorten' means 'put into a shorter form', this is the word.
    私の名前なまえはロバートなので、皆みなは略りゃくしてボブと呼よびます。↗
    My name is Robert, so they call me Bob for short.
  • 切り詰めるきりつめるCommon
    ichidan verb, transitive verbShortening by cutting: trimming hair or a hem, paring a text down, or figuratively cutting expenses. The image is cutting off what is excess.
  • 減らすへらすJLPT N3approx.Common
    godan verb, transitive verbReally 'to decrease': reducing the number or amount of something. It fits 'shorten' only loosely — time or work you cut down on — and is not the word for shortening lengths or texts.
    ジョギングでもして体重たいじゅうを減へらすようにしなさい。↗
    Try to lose weight by jogging.

Choose 「縮める」 or 「縮まる」 for making lengths, distances or spans of time shorter (transitive vs intransitive), 「略す」 for abbreviating words or texts, 「切り詰める」 for cutting or trimming something down, and 「減らす」 only for reducing amounts.
