EXTRA- means which of the following?

Understanding the meaning of the prefix extra- helps with many English terms. Extra- means outside or beyond. It hints at something being on the outside of a boundary or beyond the usual. That’s why words like exterior describe the outside part of something, and extracellular refers to outside a cell; extraordinary means beyond ordinary. Because of that, extra- signals outside rather than inside, within, or toward. So the best answer is outside.
