What is the origin of word cough?

The word "cough" has a fascinating history, with its origins dating back to the Proto-Germanic language:

* Proto-Germanic: *khukkhōn*

* Old English: *hōh*

While the exact meaning of the Proto-Germanic word is unclear, it's likely related to the sounds produced by coughing. The Old English word *hōh* evolved into the modern English "cough" through a series of sound changes over the centuries.

Interestingly, the word "cough" shares a common ancestor with the German word "Husten" and the Dutch word "hoesten," all stemming from the same Proto-Germanic root.

Here's a breakdown of the word's evolution:

1. Proto-Germanic: *khukkhōn* (likely related to coughing sounds)

2. Old English: *hōh* (meaning "cough")

3. Middle English: *cough* (similar to modern usage)

4. Modern English: *cough*

So, the next time you cough, remember that you're using a word with roots stretching back thousands of years!
