Microfiber → It is formed from "micro-" (from Greek "mikros", meaning small) and "fiber" (from Latin "fibra", meaning a thread or filament). The word "microfiber" refers to a very small fiber or thread, typically used in textiles.
Think of 'small' ('micro-') threads ('fiber') coming together to create a fabric — that's what microfiber is.
