Quasi -the word

Quasi. Pronounced: Kwey' zahy.

The meaning of quasi:

Resembling, almost, “having some, but not all of the features of,”

Example: "Meet Jossy, my quasi wife." or "Meet Sami, my quasi granddaughter."

Nobody I know pronounces it Kwey' zahy. My engineering friends always pronounced it:
Kwah' zahy, (kwaz eye) as in "The boss is a quasi idiot!"
