Sound

Okay, so I'll make this one short and sweet too, or as short and sweet as I can manage! So I live south of Tacoma, WA. This area of country is often referred to as "The Puget Sound" because all along from Seattle to olympia we're right next to the Puget Sound. So I wanted to know what "Sound" meant. According to wikipedia, in reference to puget sound, sound is defined as a large ocean inlet (also referred to as deep arm of the ocean) larger than a bay, deeper than a bight, and wider than a fjord. Also sound's (in puget sounds case) can be defined as an inlet that contains large islands. Okay, hope that makes sense, it was actually difficult for me to understand from wikipedia's definition, but I get it now.
