Tsk, tsk! False etymology, Marius. It is just the Latin prefix per-, meaning 'completely', plus the same Latin root, tenax, that tenacious carries.

As a footnote: "tenacious" is also used in a physical sense, e.g.

1. The baby colobus clung tenaciously to its mother's fur.

I would not expect to see "pertinacious" used in such a context.
