The word "ceviche" is a lot like the word "taco"... there's a million ways to make it. At its most basic, it is a raw fish that's marinated in citrus juice until it's "cooked". A more scientific way to talk about it would be to say that the citrus juice denatures the protein in the fish very similarly to the way heat would when it's truly cooked - and the fish takes on the familiar firm texture and opaqueness.
Time is another variable, and is mostly a matter of personal preference. I like my ceviche almost entirely 'cooked' so I cut my fish into very small chunks and let it marinate at least an hour before consuming. If you're more into sushi-style ceviche you can use larger pieces of fish and reduce your marinating time so that the center of your cubed fish is still translucent. And if you're wanting to try ceviche but can't stomach the idea fish that hasn't been cooked with heat, feel free to skip the raw and go straight to an ingredient like the ready-to-eat salad shrimp or crab meat - I won't razz you too much. ;)
