According to Answers.com or Wiki answers:
 
"A piece of land that is surrounded by water on only three sides and connected to a main land mass on one side is called a peninsula. Florida would be a good example."
 
And from www.enchantedlearning.com:
 
"A peninsula is a body of land that is surrounded by water on three sides."
 
From dictionary.com:
 
Peninsula-an area of land almost completely surrounded by water except for an isthmus connecting it with the mainland.
 
Dick, you raise some very interesting questions. I do think that I can picture a peninsula more accurately by describing it as "surrounded on three sides" by water, otherwise, "surrounded by" does seem to imply that water would completely encircle the land mass making it an island. 
 
Since the "problem" sentence occurred in the textbook under word "usage" problems, I would concur that the word being misused is surrounded, which is what I think I remember Bill saying.

This raises many questions:

How many sides can something be surrounded by?
Can we say, "Panama is surrounded by oceans on two sides"?
Can we say, "L.A. is surrounded by the Pacific on one side"?
Do we assume things have four sides? If so, why?
If a peninsula is bordered by water on three of four sides, is it surrounded at all?

Here's a somewhat related question: If a squirrel is clinging to the side of a large oak tree, and if you walk all the way around the tree trying to see the squirrel, who keeps moving to stay on the opposite side of the tree from you, then you have walked around the tree, but have you walked around the squirrel?

Dear List Members:
 
This morning in class, the students and I came across a sentence in their grammar handbook that apparently contains a misusage of some sort that we could not identify:
 
The Keweenaw Peninsula is surrounded on three sides by Lake Superior.
 
The only explanation we could some up with is that "three sides" should be replaced with "all sides" because a peninsula only has three sides and an isthmus. Or does it have two sides?
 
Best-
