Occur synonym,synonyms of occur

Similarity: "Happen" and "occur" are very similar in meaning. They both refer to an event or situation taking place or coming to pass. For example, we can say "An accident happened/occurred on the highway" to describe an event that took place.
Usage difference: "Happen" is a more common and informal word in daily conversation. It is often used when talking about events in a general or casual way. "Occur" is a bit more formal and is often used in more technical, written, or formal contexts. For instance, in a scientific report, one might say "The reaction occurred at a specific temperature", while in a casual chat, you'd more likely say "What happened at the party last night?"

Similarity: "Take place" also means to happen or occur. It is used to describe events that have a specific time and location where they unfold. Like "The concert took place/occurred in the stadium last night" indicates that the concert happened in a particular place at a particular time.
Usage difference: "Take place" is often used when emphasizing the location or the context of an event. It gives a sense of the event having a setting or a stage where it happens. "Occur" is more neutral and can be used without emphasizing the setting as much. For example, "The meeting will take place in the conference room" focuses on the location, while "The idea occurred to me suddenly" is more about the thought happening without a specific emphasis on the place.

Similarity: "Come about" is similar to "occur" in that it refers to how an event or situation comes into being or happens. We can say "How did this situation come about/occur?" when we want to know the cause or the process that led to a particular situation.
Usage difference: "Come about" often implies a process or a series of events that lead to a particular outcome. It's used when we want to focus on the development or the origin of something. "Occur" is more about the event itself happening. For example, "The change came about due to several factors" emphasizes the reasons and the process behind the change, while "The earthquake occurred without warning" just states the fact of the earthquake happening.

Similarity: "Arise" can be a synonym for "occur" especially when referring to problems, situations, or opportunities that come into existence. For example, "A problem has arisen/occurred that needs to be solved" indicates that a problem has come up.
Usage difference: "Arise" often has a connotation of something emerging or coming up from a particular situation or context. It's commonly used with words like "from" or "out of" to show the source or the cause. For example, "Conflicts can arise from misunderstandings". "Occur" doesn't have this strong association with a specific source or origin in the same way. "Arise" is also often used in more formal or professional contexts when discussing issues or situations that need to be addressed.

Similarity: "Transpire" can mean to occur or happen, especially when it comes to events or information becoming known over time. For example, "As the story transpired/occurred, we learned more about what had really happened."
Usage difference: "Transpire" has a sense of something unfolding or becoming clear gradually. It's often used when there is a process of revelation or when events unfold in a particular way over time. "Occur" is more straightforward about the event happening. "Transpire" is also used in a more literary or formal context sometimes. For instance, "It later transpired that he had been lying" emphasizes the discovery of the truth over time, while "The event occurred as planned" is more about the event simply taking place as scheduled.
