Character Breakdown

Understanding 設計 (せっけい)

The word 設計 primarily means "design" or "plan," and it is commonly used in contexts involving architecture, engineering, software development, and other fields where detailed planning is essential. When someone uses 設計, they often imply a thoughtful, systematic approach to creating something.

Usage and Context

設計 can refer to both the conceptual planning phase and the actual detailed drawings or blueprints (設計図). It is a noun but can be combined with verbs like する (to do) to form the verb phrase 設計する, meaning "to design" or "to plan."

Common Collocations

  • 設計図 (せっけいず): design drawing or blueprint, used when referring to detailed plans.
  • 設計する: to design or plan something.
  • 建物の設計: building design.
  • ソフトウェアの設計: software design.

Register and Politeness

設計 is a neutral, formal word often used in professional or technical contexts. It is appropriate in business, academic, and technical conversations.

Common Learner Mistake

Learners sometimes confuse 設計 with 計画 (けいかく), which also means "plan." 計画 is more general and can refer to any plan or schedule, while 設計 specifically refers to design or detailed planning, especially in technical fields. To avoid confusion, remember 設計 is about the design aspect, often involving drawings or specifications.
