I know the difference between these two words. "Happen" focuses more on describing events than on the details of place and time. The "place of occurrence" usually includes the specific time and place where the activity took place. Give you a brief summary of the meaning, pronunciation and usage of these two words, and have a general understanding first ~ ~

Next, let's look at other differences between what happened and what happened:

1. "Happy" refers to the unexpected or accidental appearance or occurrence of something, with a casual tone. And "happened" means that something happened intentionally or as planned, and the tone is more formal.

Example:

I happened to see Jane in the supermarket yesterday. ?

I happened to see Jane in the supermarket yesterday.

The meeting will be held at 2 pm tomorrow. ?

The meeting will be held at two tomorrow afternoon.

2. "Willingness" can be expressed in a wider range than "occurrence" and can be used for all kinds of things, while "occurrence" can only be used for events, activities and similar situations.

Example:

-I happen to have a spare key if you need it. ?

I happen to have a spare key if you need it.

The meeting was held in Paris last year. ?

Last year's meeting was held in Paris.

3. "Willing" pays more attention to describing events, and does not involve details such as location and time. The "place of occurrence" usually includes the specific time and place where the activity took place.

Example:

-I happened to meet an old friend at the gym. ?

I met an old friend in the gym.

The wedding will be held in the church on Sunday. ?

The wedding will be held in the church on Sunday.

4. The tone of "willing" contains some contingency and possibility, while the tone of "happening" indicates that the activity is likely to go as planned.

Example:

I happened to find a rare book in the library. ?

I came across a precious book in the library.

The concert will be held as scheduled. ?

5. "Willing" can be used in affirmative and negative sentences, while "happening" can only be used in affirmative sentences.

Example:

-I happen to remember where I put my keys. ?

The game will be held in the stadium. ?

6. "Happy" can be collocated with other verbs, such as "happened to know", "happened to be", "happened to see" and "happened to have", but "happened" is usually not collocated with other verbs.

Example:

I happened to meet my old friend at yesterday's party.
