“Smaller lakes tend to put the word “lake” after the name, as in Green Lake, while larger lakes often invert the word order, as in Lake Ontario, at least in North America. In some places, the word “lake” does not correctly appear in the name at all (e.g., Windermere in Cumbria).”
@DominicX :: I didn’t know it either. I actually sat down and wrote down all the lakes I could think of looking for a pattern. I couldn’t really sense a good pattern so I went to Wikipedia. I wasn’t really expecting to find a answer there.
