* -ive: This creates an adjective, meaning "having a defect" or "imperfect". For example, "defective product".
* -ion: This creates a noun, often referring to the process of being defective or the state of being defective. For example, "defection" can refer to a defect in a material or a political betrayal.
* -less: This creates an adjective meaning "without a defect" or "perfect". For example, "defectless" (although this is not commonly used).
It's important to note that "defect" is already a noun, so adding suffixes is often used to create related words with slightly different meanings.
