Australian and New Zealand slang meaning broken, damaged, or not working properly.
Origin uncertain, possibly from German 'krank' (sick, broken) brought by immigrants, or onomatopoetic from the sound of something breaking; became established in Australian English by the early 20th century.
The word 'cronk' perfectly captures how English absorbs slang differently across the world—Australians use it constantly while most Americans have never heard it, showing how the same language can splinter into distinct dialects with their own vocabulary.
