Accessible can mean easy to get to. If the mall is easily accessible, you might be tempted to spend a lot of money on your lunch breaks.
The "within reach" definition of the adjective accessible does not just refer to physical distance. A person can be accessible if they are approachable and friendly. A celebrity that is accessible probably signs a lot of autographs and grants interviews. The word can also describe something that is easily understood. You might need to read a plot summary of a long convoluted novel — to make it more accessible or easy to follow.
