How to say "gut" in Japanese

• ガットCommon
  nounThe common word for gut as a material: catgut, used for tennis racket and violin strings. Typical contexts include restringing a racket or a violin.
  しまった、ガットが切きれた。↗

  Oh, no. I broke a string in my racket.
• 腑ふ
  nounThe anatomical sense: the internal organs or viscera. A less common word, it refers literally to the organs inside the body, not to the belly or to courage.
• ＧＵＴジーユーティー
  nounSeldom the word you want: this is the acronym ＧＵＴ, short for grand unified theory, a term in theoretical physics. Unless you are discussing physics, it is not the 'gut' you need.

Choose by sense: 「ガット」 is the stringing material for tennis rackets and violins, 腑 the internal organs or viscera, and ＧＵＴ the physics acronym for grand unified theory; none covers figurative uses like courage or instinct.
