How to say "pure" in Japanese

• 純粋じゅんすいJLPT N2approx.Common

• ピュアCommon
  na-adjective, nounA katakana loanword meaning simply 'pure'. It appears most naturally in product names, advertising and light everyday speech, where a touch of imported flavor is welcome rather than jarring.
• 無垢むくCommon
  na-adjective, no-adjectiveCovers 'pure' as innocent and spotless: an untainted, uncorrupted character, or something immaculate and free of any stain. It points to innocence or blemish-free cleanliness, not to substances that are simply unmixed.
