Sentence:  Definition 7.2 "Let f(x) be a monic polynomial of degree n over \mathbb{F}_q. If f(x) has a primitive element of \mathbb{F}_{q^n} as one of its roots, f(x) is called a <WSD>primitive polynomial</WSD> of degree n over \mathbb{F}_q." / Theorem 7.7 "For any positive integer n there always exist <WSD>primitive polynomials</WSD> of degree n over \mathbb{F}_q. All the n roots of a <WSD>primitive polynomial</WSD> of degree n over \mathbb{F}_q are primitive elements of \mathbb{F}_{q^n}. All <WSD>primitive polynomials</WSD> of degree n over \mathbb F_q are irreducible over \mathbb{F}_q. The number of <WSD>primitive polynomials</WSD> of degree n over \mathbb{F}_q is equal to \phi(q^n-1)/n. 
Meaning of the word marked with <WSD> tags:  A polynomial over a given finite field whose roots are primitive elements; "especially", the minimal polynomial of a primitive element of said finite field.
