Chapter 2: Suffixes and Combining Forms Made Easy

Chapter 2: Suffixes and Combining Forms Made Easy

  • Main focus: Identifying the foundation of medical terms and mastering word parts to decode complex terminology.

  • Foundation of terms: Most medical terms use combining forms as their foundation.

  • Universal anatomical coverage: Every body structure has an associated combining form.

  • Example of word building: Combining the word root/combining form append/o (appendix) with the suffix -ectomy (surgical removal) results in the term appendectomy.
