釋義

A prefix that attaches to another word root to form medical and scientific terms about muscles, muscle tissue, or the muscular system — for example, myopathy (muscle disease) or myocardium (the heart muscle).

例句

Dr. Okonkwo showed the students a diagram of the myocardium on the screen.

compound: myocardium (heart muscle wall)

Brooke's doctor diagnosed the muscle weakness as a rare form of myopathy.

compound: myopathy (muscle disease)

同義詞
  • musculo-

    A different prefix with the same meaning, also from Latin (musculus); 'myo-' is Greek in origin, 'musculo-' is Latin, but both appear in medical terms (myocardial vs. musculoskeletal).

  • sarc-

    A Greek prefix referring specifically to flesh or soft tissue, sometimes overlapping with muscle (sarcoma); less common than myo- in muscle-specific contexts.

文法句型

myo- + [noun/adjective stem] → noun or adjective

用法筆記

This combining form comes from the Ancient Greek word 'mys' (meaning 'mouse' or 'muscle') and is always attached to another Greek or Latin root — it never stands alone as an independent word. Most compounds with myo- are formal or medical terms, so they appear more often in textbooks and hospital reports than in everyday conversation.

常見錯誤

❌The doctor checked his myo.
✅The doctor examined his muscle tissue.
💡'Myo-' is a prefix, not a word by itself; it must be attached to another root.
❌She had a myo injury.
✅She had a muscle injury (myositis).
💡Use the full compound form (e.g. myopathy, myositis) or switch to the ordinary word 'muscle'.
