Meaning

Beginning; clue; start; origin. The first thread or opening that allows something to get underway.

A formal noun carrying the nuance of an initial point of entry or opening clue — especially used in investigations, research, and historical narrative. The phrase 端緒をつかむ (to grasp the first clue) is particularly common in journalism and crime reporting. It implies that the beginning is not incidental but a decisive moment that unlocks further progress.

Examples

1. その一冊の本との出会いが、彼の研究の端緒となった。 His encounter with that single book became the starting point of his research.
2. 捜査の端緒すらつかめないまま、事件は迷宮入りしそうだった。 Without even a clue to begin the investigation, the case seemed destined to go cold.
