Decode clinical language one meaningful piece at a time.
Lesson 6 of 12
Diagnostic and pathology suffixes
Suffixes frequently tell whether a term names pain, inflammation, a condition, or a process of observation. Similar-looking endings can have different meanings, so avoid guessing from spelling alone. A suffix may identify what a word describes without explaining its cause or severity. Massage therapists document reported information and observed findings within their scope rather than assigning medical diagnoses.
Key points
- -itis commonly means inflammation.
- -algia means pain; -dynia also refers to pain.
- -osis commonly indicates a condition or process, with meaning shaped by the root.
- -pathy means disease or disorder; it does not name a cause by itself.
- -megaly means enlargement; -emia refers to a blood-related condition.
- -scopy names visual examination; -gram is a recorded image or tracing.
- Distinguish a descriptive word from a confirmed clinical diagnosis.
