Common Mispronunciations of Psi
Not PSY
English keeps the p in the spelling and drops it from the sound, the same deal it struck with psalm and pseudonym. Greek did say both letters.
Not PSEE
The vowel is the eye of sky, which is what makes this letter name rhyme with chi and phi.
Tip: Psi also abbreviates pounds per square inch, and in that use it is read out letter by letter as pee-ess-eye.
