Character Breakdown

Meaning and Usage

"適性" (てきせい) refers to a person's natural aptitude or suitability for a particular task, job, or role. It often implies an inherent ability or compatibility rather than learned skills.

Common Contexts

This word is frequently used in career counseling, education, and recruitment to discuss whether someone is well-suited for a specific profession or activity. For example, "適性検査" means an aptitude test designed to evaluate this suitability.

Collocations and Patterns

  • 適性がある: to have aptitude for something
  • 適性がない: to lack aptitude
  • 適性検査: aptitude test

These collocations help express whether someone fits well with a job or task.

Register and Nuance

"適性" is a formal noun often used in professional or academic contexts. It is not casual and usually appears in written or polite spoken Japanese.

Common Learner Mistake

Learners sometimes confuse "適性" with "能力" (ability). While "能力" refers to skills or capacity, "適性" emphasizes natural fit or suitability. For example, you might have the ability to do a job but lack the "適性" to enjoy or excel at it.
