The word "broad" means "wide" but has a slightly different feeling and is used to describe different things. "Broad" has a more positive and pleasant sound than "wide". A man with "broad shoulders", for example, has wide shoulders that make him look attractive. Other things that are often described as "broad" are:

• a broad smile (This is how someone smiles when they're really honest and happy.)
• a broad street (Think of a wide street in a nice little town.)
• a broad range of different things (meaning a lot of different things)
