釋義

a word element of Greek origin that is put at the beginning of medical and scientific terms to show a connection with bones or bone tissue — for example, in words describing bone diseases (osteoporosis), bone surgeries (osteotomy), or types of bone cells (osteoblast).

例句

Rania's grandmother was diagnosed with osteoporosis after a routine bone density scan at the clinic.

compound: osteoporosis = osteo- + porosis (bone thinning disease)

Dr. Eliska treated Bao's chronic back pain with osteopathy instead of surgery.

compound: osteopathy = osteo- + -pathy (bone treatment method)

同義詞
  • osseo-

    the Latin-derived combining form for bone (from os, ossis); found in terms like osseous or ossify, but much rarer than Greek-derived osteo- in modern medicine

  • bone

    the everyday English word; osteo- is restricted to formal medical and scientific compounds

文法句型

oste- + [vowel-starting element]

osteo- + [consonant-starting element]

用法筆記

The base combining form is osteo-, but the final -o- is dropped before a word element that begins with a vowel (e.g. oste- + -itis → osteitis, oste- + -oma → osteoma). The same drop rule applies to many Greek combining forms (cardio-/cardi-, neuro-/neur-).

常見錯誤

💡the combining form is osteo-, not ostere-.
❌The doctor recommended osteo-opathy.
✅The doctor recommended osteopathy.
💡-opathy starts with a vowel, so oste- is used, not osteo-.
