Which prefix means lack of or absence of?

Explanation:
A-/An- denotes absence or lack of something. This negative prefix negates the root word, signaling “without” or “not.” For example, anaerobic means without oxygen, anhydrous means without water, and anemia refers to a lack of healthy red blood cells or hemoglobin. In contrast, peri- means around, endo- means within, and neo- means new, so they don’t convey absence.
