連結（れんけつ、renketsu）
- connection

The Japanese word 連結 (れんけつ, renketsu) means "connection," "link," "coupling," or "joining." It refers to the act of connecting or joining things together, either physically or metaphorically. This can apply to various contexts, such as connecting train cars, linking ideas, or establishing relationships. The core idea is the act of bringing separate entities together to form a whole. 連結 implies a more formal or technical connection compared to casual words like つなぐ (tsunagu, "to connect") or つなげる (tsunageru, "to join/connect").

You can use 連結 in various situations where you need to describe the act of connecting things. It's suitable for formal or technical contexts, such as business reports, technical manuals, or news articles. It's less common in casual conversations among friends. Phrases that include 連結 are often used in business or technical fields, when a technical linkage or integration is required.

連結 is primarily written using the kanji 連結, but can also be written in hiragana れんけつ for learners. Katakana is rarely used. The okurigana is usually "する" (suru), making the verb form 連結する (renketsu suru, "to connect").
