infectious laryngotracheitis
C2Highly Technical/Veterinary
Definition
Meaning
A specific viral respiratory disease of chickens and other birds, causing inflammation of the larynx and trachea.
The term is strictly confined to veterinary medicine and poultry science, referring to a contagious infection of the upper respiratory tract in gallinaceous birds, primarily caused by Gallid alphaherpesvirus 1 (GaHV-1).
Linguistics
Semantic Notes
This is a compound noun where the first element 'infectious' specifies the communicable nature of the disease, and the second, more complex element 'laryngotracheitis' is a clinical term combining 'larynx' (voice box), 'trachea' (windpipe), and the medical suffix '-itis' (inflammation). Its meaning is non-compositional for laypeople.

Learning
Memory Aids
Mnemonic
Think: INFECTIOUS = spreads easily, LARYNGO = relates to the voice box/larynx, TRACHE- = windpipe/trachea, -ITIS = inflammation. So, 'an easily spread inflammation of the bird's throat and windpipe'.
Conceptual Metaphor
DISEASE AS AN INVADER (The virus invades the respiratory tract).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate 'laryngotracheitis' word-for-word as 'ларинготрахеит' and assume it refers to the common human childhood illness. In English, it is exclusively an avian disease. The human condition is 'croup' or 'laryngotracheobronchitis'.
Common Mistakes
- Pronouncing 'laryngotracheitis' as if it were a common word (stress is on '-ti-').
- Using it to describe human illnesses.
- Misspelling as 'laryngotrachitis' or 'larygotracheitis'.
- Assuming 'infectious' is redundant and dropping it; in the field, the full name is standard.
