Language is funny at times. Eg:
Message received from the front line in battle: Send three and four pence, we're going to a dance.
Actual message:SpoilerSend reinforcements, we're going to advance!
Some common words:
Cache - kay-sh (some say cash)
Router - r-out-er (Yanks say roo-ter)
Data - dah-ta (some say day-ta)
ISO - eye-so
Which is from the Greek Isos; it is a word not an abbreviation.
It is the short form for the International Organisation for Standardisation – wacky hey!
They define it so it must be http://www.iso.org/iso/about/discover-iso_isos-name.htm
Nikon - nik-on (Yanks sometimes say nigh-kon)
What weird word variations have you heard?
