word usage - When talk about an example sentence, which preposition should I use,"of", "about" or "for"?

I asked a question just now

The Oxford dict gives this example of except.

"except" is the word I was considering. I searched it on Oxford dict, and got the sentence above.

Is the sentence an example of the word "except"

or

for the word "except"

or

about the word "except"?

Answer

Example is usually paired with of. See this ngram.

Usually, it's an example of [a noun].

• Your dog is an example of good training.


• That poem is a good example of a haiku.


• My cookbook has several examples of French cooking.

More rarely, we can have "example for" in sentences like:

• You need to set a good example for your younger siblings.



• This merger sets an example for other companies to follow.

"Example about" is uncommon.
