to the extent to which

[capcap23]

Provided the ''to'' isn't the preposition of the noun that comes before it, Is it correct to say ''to the extent to which''?

For example, ''to the extent to which I know, It isn't mammal.''.

See above. We have told you over and over again not to use a capital letter after a comma unless the next word is a proper noun. It's a really simple rule - PLEASE learn it.

I think you need to come up with a different example. Your example sentence means nothing. I assume you mean "As far as I know, it isn't a mammal". You can't use anything like your "to the extent to which" phrase instead of "As far as I know".

The phrase "to the extent to which" can be part of a grammatical sentence.

I have read somewhere that ''as far as'' and ''to the extent that'' are interchangeable when used to say something in terms of your best knowledge.

To the extent that he encouraged their bad behavior, he's to blame for it. /original
To the extent to which he encouraged their bad behavior, he's to blame for it. / Would this one work?

1) To the extent that he encouraged their bad behavior, he's to blame for it.

That's fine.


2) To the extent to which he encouraged their bad behavior, he's to blame for it.

This means the same as 1, so there's no reason to use it when you can just use 1.


3) as far as I know

This is very natural.


4) to the extent to which I know

This is not natural. Don't use it.

Could it be that I misjudged the situation? I don't know to the extent, in fact, I do know the extent. Then ''to the extent which I know'' should work but in either way, I'm suprised ''1)'' is considered fine with no ''to'' at the present time.

I'm sorry, I don't understand what you're saying.

The correct phrase is as far as I know. This phrase is equivalent to to the best of my knowledge.

As far as I know, it's a mammal.

This means that you think it is a mammal, although you concede that you may be mistaken.

Don't use To the extent to which I know in this sentence.

This is not natural. Don't use it.

Is the same valid for ''to the extent that I know''?
