Plural of croup; either multiple instances of the respiratory condition croup, or multiple instances of the horse anatomy croupe.
Plural of croup, from Scottish origin (possibly imitative of the sound). The word has been used since the 17th century in English to describe the respiratory disease.
The word 'croup' is wonderfully onomatopoetic—the name literally mimics the harsh, barking sound the disease makes, so hearing 'croups' would mean hearing multiple kids making seal-like sounds!
