What fruit did Adam and Eve eat in the garden?

The Bible does not specifically say what kind of fruit it was other than it was from the tree of the knowledge of good and evil. Some have speculated it was an apple because the Latin word for apple is malus, which is similar to the word for evil. Yet others believe it was a fig because, they argue, apples don’t grow in that part of the world. We truly don’t know what kind of fruit it was. People have come to accept it as an apple because, in the English language, the word “apple” is etymologically (or the source word, root word) a generic term including all fruits, berries and nuts.
