...is PNEU, the French word for "tire".
The "P" is pronounced, and so the word almost gets blurted out. I think it just sound so funny.
I was teaching my youngest son the word, and when he repeated it, I told him it sounds like a sneeze, and so I said "Bless you!"
Now, as I researched the word, I learned:
To breathe. Imitative root. 1. sneeze, from Old English fnosan, to sneeze, from Germanic *fneu-s-. 2. snore, snort, from Old English fnora, sneezing, from Germanic *fnu-s-. 3. apnea, dipnoan, dyspnea, eupnea, hyperpnea, hypopnea, polypnea, tachypnea, from Greek pnein, to breathe, with o-grade nouns pnoi, -pnoia, breathing, and pno, breath. 4. Suffixed form *pneu-m. pneuma, pneumatic, pneumato-, pneumo-, from Greek pneuma, breath, wind, spirit. 5. Germanic variant root *fnes-. sneer, from Old English fnran, to snort, gnash one's teeth. (Pokorny pneu- 838.)
