It’s boardwalk, not broadwalk.
I am not a journalist, so I am not here to correct people’s grammar. In fact, I make that mistake myself. It seems like a NY thing because most New Yorkers are the ones that make this mistake.
Is it because we have “Broadway,” one of the most popular streets in North America, programed into our subconscious? “Board” and “broad” rhyme, and they do have the same letters, which makes them anagrams of each other. So it’s not the worst mistake you can make mixing them up. The boardwalk is a very broad walk and it’s made of boards. It’s a spacious, wooden walk. So yeah, I can see how people make that mistake.
Still having problems remembering that it’s board and not broad? Just think of the famous Drifters song:
(Under the boardwalk) we’ll be havin’ some fun
(Under the boardwalk) people walking above
(Under the boardwalk) we’ll be faling in love Under the board-walk (board-walk!)
