Difference between 推迟, 拖延, 延迟, and 推延
Hello,

I was interested in knowing the differences in meaning between 推迟, 拖延, 延迟, and 推延. To me, they all mean "to postpone, to delay". I was wondering if someone can provide accurate definitions for each, explain differences between the four terms, and provide example sentences.

Hello,

Answer

Thank you for the explanations. These are very helpful.

Answer

推迟：王老师临时有事，把下午的课推迟到下周上。 
拖延：你不能因为王老师不上课就拖延交作业啊。 
延迟：王老师直播给我们上课，可惜画面有些延迟。 
在大多数情况下，推延=推迟，推延更偏向书面用语，推迟偏向口语化。

Answer

推迟 is a neutral word, states a fact. For example, there is raining today so the university 推迟 sports meet.
拖延 is to say someone procrastinates
延迟 is to 推迟 to a later time
推延 is quite similar to 延迟
I feel the difference between 推延 and 推迟 is that 推延 usually describe making something keep happening until a later time, but 推迟 is to let something happen at a later time.
