inject

　injectにはこんな使い方もあるのですね。「資金を注ぎ込む」という意味で使われています。語源はin（〜の中に）＋ject（投げる）なので，やはり「投げる」が共通イメージにありますね。「投与する」「投資する」と日本語でもあてることができます。LDOCEでは，to provide more money, equipment etc for somethingと定義されています。例文として，They need to inject more money into sports facilities.が挙げられています。以下の文章でもそうですが，この意味で使われるときは，intoと共起します。

　Seiji Maehara, state minister for national policy, said he asked Yamanaka over the phone for advice on how government policy can support his research.
　"We must properly inject money into science and technological fields that need to be developed," Maehara said.
