When we encounter obstacles that impede our progress or delay our plans, we often use the phrase "have a hold up on." However, there are several synonyms to convey similar meanings. For instance, to "delay" something means to postpone until a later time. "Hinder" implies obstacles or challenges that slow down or prevent progress. "Thwart" suggests a deliberate or intentional obstruction that frustrates one's objectives. "Stall" is a term often used for temporary delays or interruptions. Finally, "deter" means to discourage or dissuade, implying that certain obstacles make the pursuit no longer worthwhile. All these synonyms can be used interchangeably based on the context.
