Definition

At first; at the beginning.

colloquialtime

How it's used

Focuses on the initial stage of a process or a narrative rather than just a point in time. It often implies a contrast between the starting situation and how things developed later. While interchangeable with 初初 in many contexts, it carries a slightly more formal or narrative tone.

Examples

At first he wouldn't say, but later he was willing to.

Common phrases

at the very beginning

Common mistake

Do not confuse this with 開頭, which is more commonly used in casual speech to describe the start of a story or a sequence of events. Using 開首 in very informal conversation can sometimes sound slightly stiff or literary.
