as of

[Buno]

Hi Everyone,

Could you help me understand the difference between:
"this kind of studies has been carried on for long time"
and
"this kind of studies has been carried on as of long time"

I found the form "as of" in the dictionary but I cannot understand in which context I can use it. in fact I think that the way I used it is not correct.

thank you,

Buno :shock:

Hi Buno,
"as of (a time)" means up/by (a time). Look at this sentence:
As of last week he was still unmarried.
It is equal to: Up to last week he was still unmarried.

Sometimes it also refers to "in term of; considering" Eg:The property belongs to her as of right.
It is equal to:The property belongs to her in terms of right.

That is my understanding. Hope helpful!

"as of" also means "from".
"As of today, we'll do it my way".
So, you can see it means two opposite things: up until, and from/since. For this reason, it's best avoided, in my opinion. There are always better, less ambiguous options.

"As of 20th May, we had $15,000." ->
"Up until 20th May, we made $15,000."
"On 20th May, we had $15,000."

"As of today ..." -> "From today ..."
"As of 21st May, we've made $7,000" -> "Since 21st May ..."

If you see "as of" sometimes you have to guess from the context what it means.
