How to say "absolute" in Japanese

• 純然じゅんぜんCommon
  taru-adjective, adverb (with と)Covers the 'utter, sheer' sense: something is purely that thing and nothing else — a pure-and-simple lie, a purely personal matter. For unconditional authority or 'definitely,' it is not the word you want.
• 絶対的ぜったいてきCommon
  na-adjectiveThe plain adjective for 'absolute': it describes something — power, authority, trust — as unqualified and admitting no exceptions. Use it when you need 'absolute' as an adjective before a noun.
  コンピューターは現在げんざいでは絶対的ぜったいてきな必需品ひつじゅひんである。↗

  A computer is an absolute necessity now.
• 絶対ぜったいJLPT N3approx.Common
  no-adjectiveCovers the unconditional, no-exceptions sense of 'absolute' — absolute obedience, an absolute rule — and also works adverbially meaning 'definitely, no matter what,' as in 'absolutely not.'

絶対 covers the unconditional, no-exceptions sense and the adverbial 'definitely'; 絶対的 is its adjectival counterpart, describing something as absolute; 純然 really means 'sheer, pure and simple,' so it is seldom the word for 'absolute' itself.
