How to say "insert" in Japanese

Choosing the right word
  • 差し込むさしこむCommon
    godan verb, transitive verbCovers physically inserting or thrusting something into something else, including plugging in. Typical when you push an object into an opening or slot, such as plugging a cord into a socket.
    しかもなお、石いしの大おおきいブロックが非常ひじょうにぴったりと合あわさっているので、ブロックの間あいだにナイフの先さきを差し込さしこむことができない。↗
    And yet the large blocks of stone are fitted together so closely that you cannot put in the point of a knife between them.
  • はめるJLPT N2approx.Common
    ichidan verb, transitive verbFor inserting something that fits snugly into a recess or frame, like a cork or a pane, or fastening a button. The nuance is fitting a part into a space shaped to receive it.
    His portrait was mounted in the fancy frame.
  • 組み込むくみこむJLPT N1approx.Common
    godan verb, transitive verbMeans to insert something as a component within a larger whole, and is better understood as 'incorporate' or 'build in'. Use it for adding an element into a system, plan, or structure rather than for physical insertion.
    モデムはコンピューターの中なかに組み込くみこまれた。↗
    The modem was built into the computer.
  • 刷り込むすりこむCommon
    godan verb, transitive verbA printing term: to print something on or into a page, such as an illustration, or to stencil a pattern. It is seldom the word you want for ordinary 'insert'; use it only when the insertion is done by printing.
  • 入れるいれるJLPT N5approx.Common
    ichidan verb, transitive verbThe broadest and most general choice: to put something in, or let or take something in. When no more specific nuance like plugging, fitting, or incorporating applies, this is usually the safe default for 'insert'.
    それは引き出ひきだしに入いれておきました。↗
    I put it in the drawer.

Use 「入れる」 as the general 'put in' default; 「差し込む」 for pushing or plugging something in, 「はめる」 for fitting something snugly into a recess, 「組み込む」 for incorporating something into a larger whole, and 「刷り込む」 only for printing.
