I second Lizzy B And Ahmadi Nader Eddine. For a very different meaning: I would use "hold over" in the phrase "hold over someone('s head)" which would be used to mean blackmail, or to not forget a promise that someone made, especially one that they didn't actually mean. In other words, you have past information about someone or something they said and you are using it to your advantage. E.g. He did the company a small favour ONE time over a decade ago, and now he is still holding it over the CEO to get all sorts of tax benefits. What? I'm not buying you front row seats! I can't believe you're still holding that over my head, I was joking!

I haven't heard a 'hold over' in that sense, 'hold off' is more common to mean 'delay'. Hold off, put off, postpone and delay are all very similar, they all mean to do something later than originally planned. Hold off (on): (when we mention a verb after, we use the structure 'hold off on ___ing') I wanted to talk to him, but I saw he was busy, so I decided to hold off. I will talk to him later. You should hold off on calling the doctor until you get your medical results back. (Wait until you get your results back, then call the doctor. Don't do it now.) Put off: (this can mean to not do something, or to make someone not want to do something) I really need to finish my essay – I keep putting it off. (Every day I say, 'not today, I will do it tomorrow') The film 'Jaws' put a lot of people off swimming. They were scared by the movie, and they didn't want to swim after watching it. Postpone: I know we agreed to have coffee this afternoon, but can we postpone till tomorrow? I am busy today. The boss is sick so we need to postpone the meeting. Delay: (this is like postpone, but can describe actions that are out of our control) The weather is really bad, and I think it will delay our flight. (even better: I think our flight will be delayed)* If you don't love her, you need to break up with her. Stop delaying the inevitable! *A flight can be delayed or postponed, but if it is DELAYED, it will still happen today, just a few hours later than the original time. If it is postponed, it will not happen today. Maybe the airline will give you a ticket for a flight on a different day.

"Hold over," "put off," "postpone," and "delay" are all terms that generally convey the idea of causing something to happen at a later time than originally planned, but they may have nuanced differences in usage and context: Hold Over: Meaning: To extend the duration or continuation of something. Usage: Often used in the context of maintaining or continuing a situation, event, or decision beyond the originally intended time. Put Off: Meaning: To delay or postpone something. Usage: Generally interchangeable with "postpone" and "delay." It's a more casual term and can be used in various contexts, such as meetings, appointments, or events. Postpone: Meaning: To reschedule an event or activity to a later time or date. Usage: Commonly used when referring to the intentional rescheduling of planned events, meetings, or activities. Delay: Meaning: To make something happen at a later time than originally planned or expected. Usage: A broad term that encompasses the general idea of slowing down or deferring a process, action, or event. While these terms share similarities, the choice of which to use may depend on the specific context and formality of the situation. In many cases, they can be used interchangeably, but certain contexts may lend themselves more naturally to one term over the others.
