Character Breakdown

Meaning and Usage

「一連」(いちれん) refers to a connected series or chain of events, actions, or items. It is often used to describe things that happen in succession or are grouped together logically or temporally.

Common Contexts

You will frequently see 「一連」 used in formal or written Japanese, especially in news reports, business, or official documents to describe sequences such as incidents, processes, or collections of related items.

Collocations and Patterns

  • 一連の事件 (いちれんのじけん): a series of incidents
  • 一連の作業 (いちれんのさぎょう): a series of tasks or operations
  • 一連の流れ (いちれんのながれ): a sequence or flow

These collocations emphasize the connectedness and order of the items or events.

Nuances and Tips

When using 「一連」, the speaker implies that the items or events are linked and should be considered as a whole. It is more formal and specific than simply saying "series" or "sequence". Avoid using it for casual or unrelated lists.

A common learner mistake is confusing 「一連」 with 「連続」 (れんぞく), which also means "continuous" or "consecutive" but focuses more on uninterrupted succession rather than a logically connected series. Use 「一連」 when the emphasis is on the relatedness and grouping of the items.
