How it's used
Expresses an original intention or plan that has since changed or been interrupted. It functions similarly to 'originally' or 'initially' but carries a stronger sense of an expectation that failed to materialize. It is frequently used to explain why a current situation differs from the initial arrangement.
Examples
He was supposed to come today, but he didn't show up in the end.
Were you originally planning to go see a movie?

Common mistake
Learners often confuse this with 本來, which is more standard. While they are interchangeable, 原底 feels slightly more informal and is very common in spoken Cantonese to highlight a discrepancy between the past plan and the current reality.
