The phrasal verb "set back" is primarily used in informal speech, though it can appear in more casual formal settings such as business meetings or reports. It typically refers to delaying progress or causing a postponement in plans, projects, or schedules. You might hear it in contexts such as project management, where an unexpected issue might "set back" the timeline. It's also used when unexpected expenses arise, indicating a financial loss or inconvenience, e.g., "The car repairs really set me back." Despite its informal roots, it is understood in formal contexts for its ability to succinctly deal with the concept of delays or financial repercussions. Generally, it connotes a negative impact or minor hindrance, the severity of which depends on the context.
