root words
- Meaning: The transcript lists common combining forms used in medical terminology along with their meanings. Some entries include variant spellings.
- alg(o)-, alge-, algesi(o)-: pain
- arthr(o)-: joint
- bacteri(o)-: bacteri
- cerebr(o)-: cerebri
- cyan(o)-: blue
- dermat(o)-, derm(o)-: skin
- erythr(o)-: red
- gluc(o)-: sugar
- leuk(o)-: white
- melan(o)-: black
- myel(o)-: spinal
- pancreat(o)-: pancre
- poli(o)-: gray
Variants and Notes
- Some combining forms appear with multiple spellings to reflect different etymological sources (e.g., dermat(o)- and derm(o)- both meaning skin).
- The list includes both the prefix form (e.g., alg(o)-) and, in some cases, the stem without the trailing vowel (e.g., pancreat(o)- vs. pancre-). The transcript shows pancreat(o)- pancre as the stem related to the pancreas.
- For cerebr(o)-, the accompanying form given is cerebri, indicating the related root form used to denote the cerebrum.
- The entry poli(o)- is given as meaning gray; this root appears in terms like poliomyelitis (literally from Greek polios = gray, referring to gray matter in the spinal cord).

Practical Takeaways
- These combining forms are used to build medical terms by combining with suffixes (e.g., -itis, -pathy, -ology) to convey specific meanings.
- Variants (e.g., dermat(o)- vs. derm(o)-) are common and reflect historical/etymological origins; recognizing both helps with decoding unfamiliar terms.
- Understanding the root meanings aids in parsing complex terms and deducing their medical implications quickly.
