pain in a joint

arthritis
osteoarthritis
arthralgia
arthroalgia

Explanation:

Analyze the definition

The target definition is "pain in a joint".

Break down the word parts

• The combining form for joint is "arthr/o".
• The suffix for pain is "-algia".
• Combining these parts yields "arthralgia".

Evaluate the options

• "Arthritis" means inflammation of a joint ("-itis" = inflammation).
• "Osteoarthritis" means inflammation of the bone and joint ("oste/o" = bone).
• "Arthralgia" correctly translates to pain in a joint.
• "Arthroalgia" is misspelled; when combining "arthr/o" and "-algia", the combining vowel "o" is dropped because the suffix begins with a vowel.

Answer:

• Arthritis
• Osteoarthritis
• Arthralgia (Correct answer)
• Arthroalgia
