Definition
Meaning
A neurological disease of humans and animals caused by excessive consumption of certain legume seeds of the genus Lathyrus.
The condition is specifically linked to a toxin found in certain peas (like grass pea or chickling pea) and is characterized by spastic paralysis, muscle weakness, and permanent skeletal deformities.

Examples
By Part of Speech
adjective

Examples
By CEFR Level
- Consuming large amounts of grass peas can lead to a disease called lathyrism.
- Lathyrism causes problems with walking and muscle control.
- Public health officials identified the cause of the paralysis as lathyrism, resulting from the population's over-reliance on Lathyrus sativus during the famine.
- The toxin BOAA, implicated in lathyrism, is a potent excitatory amino acid that damages motor neurons.

Memory Aids
Mnemonic

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'latyr'' (латырь) meaning 'armour' or 'chainmail' in old Russian; the words are not related. The Russian equivalent is 'латиризм' (latirizm), which is a direct borrowing.
Common Mistakes
- Misspelling as 'lathyrism' (dropping the 'h').
- Pronouncing the 'th' as voiced /ð/ instead of voiceless /θ/.

FAQ
Frequently Asked Questions
No, lathyrism is not contagious. It is a toxicological condition caused by ingesting the neurotoxin found in specific legumes.
There is no specific cure. Treatment is supportive, focusing on managing symptoms. Prevention through dietary diversification and avoiding excessive consumption of implicated legumes is key.
It is historically associated with regions of Asia and Africa, particularly during famines or droughts when hardy but toxic legumes like grass pea become a staple food.
It primarily affects the nervous system (neurolathyrism), leading to spastic paralysis of the lower limbs. A related form, osteolathyrism, affects connective tissue and bone.
