How to say "assignment" in Japanese

  彼かれが重要じゅうような役やくを果はたした。↗

  He played an important part.
• 指定していJLPT N2approx.Common

  When applying for tickets, please give alternative dates.

  noun, suru verb, transitive verbThe legal and commercial sense: assignment as the transfer or conveyance of rights or property from one party to another. This is the word for legal 'assignment'; it does not cover tasks or schoolwork.
• 宿題しゅくだいJLPT N5approx.Common
  nounThe schoolwork sense: homework — an assignment a teacher gives students to complete, typically outside class. When 'assignment' means schoolwork, this is the word you want.

  I have no homework today.

'Assignment' splits by sense: use 宿題 for schoolwork, 配属 for assigning a person to a unit or workplace, 役 for a role or duty, 指定 for designating or specifying something, and 譲渡 for legal transfer of rights or property.
