Somebody asks a very old lady "How old are you"? And she says:

"I am 101. Did you know anybody else that old?" Old lady (see:00:49-00:53)

I sometimes hear that another structure is also used when comparing two things. For instance for the case above:

"Did you know anybody else as old?"

When comparing things, "....that old" and "....as old?" both seem to have the same meaning.

So it seems that we can use both with no change in meaning, can we?

  • Can you specify usage? Because they are not (commonly) used as you described. "...that old" isn't normally a comparison between two, it means "really old". OTOH, while you can use "...as old" to compare two person, it usually comes with direct comparison, like : "Never did I see anyone as old as you are".

1 Answer 1


Actually, she says "Did you ever know anybody else that old?" She means "Have you ever met a person of that age (101)?"

That old refers to a particular age. As old [as] is a comparison. Alice could have said "Did you ever know anybody as old as I am?"
