How to say "conceptual" in Japanese

• 観念的かんねんてきCommon
  na-adjectiveCovers 'conceptual' in the sense of notional or ideational — existing as an idea rather than as something concrete or practical. Use this for abstract arguments, plans, or distinctions that remain purely in the mind.
• 理念的りねんてき
  na-adjectivePoints to 'conceptual' as relating to ideals or guiding principles (理念) rather than to practical reality. Suits talk of visions, missions, or value-driven stances; it is less common and narrower than 観念的.
• コンセプチュアル
  na-adjectiveA loanword for 'conceptual', found chiefly in art, design, and business contexts, as in conceptual art. Handy when the katakana feel is wanted, but not a general-purpose replacement in ordinary prose.
• 概念的がいねんてき
  na-adjectiveRelates to concepts (概念) as units of thought; its first gloss is 'general', so it often means something like 'at the level of a concept' or 'broadly, in outline'. A less common choice for 'conceptual' proper.

観念的 is the default for 'conceptual' in the sense of existing only as an idea rather than concretely; 理念的 leans toward ideals, 概念的 toward concepts as categories, and 「コンセプチュアル」 is a loanword used mainly in design and art talk.
