[verb た-form] + ばかり
The structure たばかり is used to express that an action has just been completed or that something just happened. It emphasizes the recency of the action – the speaker feels that not much time has passed since it occurred.
Attach ばかり to the た-form of a verb to indicate that the action was just done.
An important nuance of たばかり is that "just" is subjective. It doesn't necessarily mean seconds or minutes ago – it reflects the speaker's feeling that the event was recent. Depending on context, it could refer to something that happened hours, days, or even weeks ago.
Even though a month has passed, the speaker still feels the move was recent.
たばかり is often followed by なので, だから, or で to explain a reason or consequence related to the recently completed action.
It can also be followed by なのに to express surprise or frustration that something has already changed despite the action being recent.
Both たばかり and たところ can mean "just did," but they differ in nuance. たところ focuses on the immediate moment right after an action is completed (seconds or minutes), while たばかり is more flexible and emphasizes the speaker's subjective sense that not much time has passed. たところ cannot be used for something that happened weeks ago, but たばかり can.
