How to say "philosopher" in Japanese

• 哲人てつじんCommon
  nounCovers the sense of a wise or sage-like person rather than an academic philosopher; best for someone admired for profound wisdom, such as a respected elder or sage.
• 哲学者てつがくしゃ
  nounThe standard word for a philosopher as a student or practitioner of philosophy, whether academic or historical; this is the usual choice when 'philosopher' refers to the discipline.
  あごひげがあるだけでは哲学者てつがくしゃにはなれぬ。↗

  The beard does not make the philosopher.
• フィロソファー
  nounA loanword meaning philosopher; it is less common and largely overlaps with 哲学者, so it is rarely the word you need — prefer the native term in most contexts.
• 哲てつ
  nounGlossed as sage, wise man, or philosopher, but as a standalone word it is uncommon and marginal for 'philosopher'; it is not the ordinary way to refer to one.

Use 哲学者 for a philosopher in the academic sense; 哲人 for a wise, enlightened person; 「フィロソファー」 is a marginal loanword; 哲 is not used alone for 'philosopher'.
