Is eggplant a fruit or vegetable?
The confusion by the others answering this question comes from the difference between a botanical answer and a food answer. Botanically, a fruit is the ripened ovary—together with seeds—of a flowering plant. In many species, the fruit incorporates the ripened ovary and surrounding tissues. Fruits are the means by which flowering plants disseminate seeds. In cuisine, when discussing fruit as food, the term usually refers to those plant fruits that are sweet and have a soft flesh like plums, apples and oranges. Many common ‘vegetables’, as well as nuts and grains, are the fruit of the plant species they come from. This includes sweet corn, cucumbers, bell pepper, tomato, etc. So, the answer to your question is, yes, an eggplant is a fruit that is eaten as a vegetable.
