Greek suffixes

Description of pain syndromes and pathologies

To denote pain sensations in various parts of the body, the suffix -algia is traditionally used. When attached to a Greek root, it forms a full clinical diagnosis.

Common combinations with the suffix -algia:

• arthralgia — joint pain;
• cephalalgia — headache;
• gastralgia — stomach pain;
• myalgia — muscle pain;
• odontalgia — toothache;
• proctalgia — rectal pain.

Another important suffix is -stasis, which indicates stagnation, cessation of fluid flow, or a physiological process. Physicians frequently encounter conditions such as cholestasis (bile stasis), lymphostasis (lymph stasis), coprostasis (fecal stasis), and urostasis (urine stasis). Belonging to the same group is haemostasis — the process of stopping bleeding. When referring to the inhibition of bacterial growth, the term bacteriostasis is used.

Surgical interventions and manipulations

Greek suffixes allow for a detailed description of the nature of a surgical operation. The most common suffix, -tomia, translates as "incision" or "opening".

Examples of using -tomia:

• laparotomia — opening of the abdominal cavity;
• thoracotomia — opening of the chest cavity;
• tracheotomia — incision of the trachea;
• osteotomia — bone incision.

In addition to incision, other types of surgical interventions are distinguished. For example, to denote fixation or attachment of an organ, the suffix -pexia is used (colpopexia — fixation of the vagina). Restoration of the form or structure of an organ is conveyed by the suffix -plastica, and the creation of an artificial opening (fistula) by the suffix -stomia. The process of tissue suturing is designated as -r(r)haphia, as seen in the term neurorrhaphia (suturing of a nerve), and the release of an anatomical structure from scars as -lysis (neurolysis).

Names of medical instruments

To denote equipment used in diagnostics and treatment, specialized suffixes indicating the device's function are used.

Devices for examining (inspecting) cavities and surfaces (suffix -scop):

• endoscop — for examining internal cavities;
• laparoscop — for inspecting the abdominal cavity;
• ophthalmoscop — for examining the ocular fundus;
• otoscop and rhinoscop — for examining the ear and nose, respectively;
• phonendoscop — for auscultation of sounds;
• gastroduodenoscop — for examining the stomach and duodenum.

Devices for measuring physiological parameters (suffix -metr):

• spirometr — measurement of respiratory parameters;
• pulsotachometr — determination of pulse rate;
• oxyhemometr — measurement of blood oxygen levels;
• algezimetr — assessment of pain sensitivity;
• tonometr — measurement of pressure or tissue tension.

Prefixes affecting term meaning

In medical Latin, certain prefixes and initial term elements function in close conjunction with suffixes, radically changing the meaning of the word.

The dys- prefix indicates a disorder or functional impairment. It forms such concepts as dysbacteriosis, dystonia (tone disorder), dyspnoë (breathing disorder), dysphagia (swallowing disorder), and dyskinesia (movement disorder).

The macr(o)- element signifies a large or oversized organ:

• macrocephalia — abnormally large head;
• macroglossia — enlarged tongue;
• macrodactylia — enlarged fingers/toes.

The element olig(o)- indicates a small quantity, scarcity, or insufficiency. It is used to form terms describing deficiencies: oliguria (decreased urine output), oligopnoe (shallow or infrequent breathing), oligokinesia (hypokinesia), oligosialia (decreased salivation), and oligophrenia (intellectual disability, oligophrenia).
