There is / There are

Logic does not always govern grammar.

For example, which sentence sounds correct: There is more than one way to use these trails.
OR There are more than one way to use these trails.

Native speakers of English vote for the first: There is. Yet logically the subject of is/are is the nominative more. You would think that more would be plural, especially in the phrase more than one.

For this example, I am grateful to my collegiate godson, Bill Egan. He it was who, at age four, presented me with my favorite example of how idiosyncratically English treats its pronouns. Counting a number of objects and holding up two fingers, he said, "I have two--these many." Logically, his grammar would seem correct: if the substantive many is more than one, you would think it should be described by "these," not the standard "this."

The good news: my Microsoft grammar checker will catch There are more than one way. The bad news: It will not catch I have these many toys. (Granted, an advanced speaker might intend these and many to describe the noun independently. "I give unto you these many privileges.")

How do foreigners ever learn our language?
