日本語の意味

実行時に構築可能で、パラメータとして渡され、関数から返され、変数に代入できるエンティティ（プログラミング言語における「ファーストクラスオブジェクト」）

In many modern programming languages, a function is treated as a first-class object that can be created at run time, passed as a parameter, returned from other functions, or assigned to variables.

多くの現代のプログラミング言語では、関数は実行時に生成され、引数として渡され、別の関数から返され、変数に代入できる第一級オブジェクトとして扱われます。
