One of the most...
In one of the discussions here, Brian W. tells me that the following sentence is wrong:
“This is one of the most common errors people make…”
He says it should be: “One of the more common…”
Proper use of ‘most’ requires the size of the set in which the subject is a member: “one of the 10 most.” Without a numeric qualifier, all but the last are potentially included in the set “one of the most.” That (unfortunately) makes it as meaningful as “up to 10… or more!”
Now, is this a grammatical issue or stylistic issue? I see “one of the most” being used quite often.
As a side note, in Japanese, “one of the most” would be an oxymoron because the concept of “most” implies that it is at the top of the list, that is, there is only one thing that could be “most” or “best”. I remember feeling awkward about the phrase “one of the most” when I was first learning English.
