question:
Passage: The concept of prime number is so important that it has been generalized in different ways in various branches of mathematics. Generally, 'prime' indicates minimality or indecomposability, in an appropriate sense. For example, the prime field is the smallest subfield of a field F containing both 0 and 1. It is either Q or the finite field with p elements, whence the name. Often a second, additional meaning is intended by using the word prime, namely that any object can be, essentially uniquely, decomposed into its prime components. For example, in knot theory, a prime knot is a knot that is indecomposable in the sense that it cannot be written as the knot sum of two nontrivial knots. Any knot can be uniquely expressed as a connected sum of prime knots. Prime models and prime 3-manifolds are other examples of this type. Question: What is an additional meaning intended when the word prime is used?
answer:
any object can be, essentially uniquely, decomposed into its prime components
