Want to sound like a good old boy who doesn’t give a hoot what
foreigners think? Say “EYE-rack.” But if you want to sound
knowledgeable, say “ear-ROCK.” Politicians who know better sometimes
adopt the popular mispronunciation in order to sound more folksy and
down to earth.

Similarly in standard English, Iran is not pronounced “eye-RAN” but “ear-RON.”

On a related matter, the first syllable of “Italian” is
pronounced just like the first syllable in “Italy,” with an “it” sound.
“Eye-talian” sounds distinctly uneducated. 

LAUNDRY MAT / LUNDROMAT

“Laundromat” was coined in the 1950s by analogy with “automat”―an
automated self-service restaurant― to label an automated self-service
laundry. People unaware of this history often mistakenly deconstruct
the word into “laundry mat” or “laundrymat.”
