Hello everyone,
In the first place , I want to apologise for bothering you . Indeed I have come across
an abbreviation that I couldn’t know it’s pronunciation . The abbreviation is " UFO".
I’m looking forward to your answer.
Thanks alot.

To pronounce this we say the letters U F O. It is an abbreviation for “unidentified flying object”, an object or light in the sky that you cannot identify. Some people might believe it is a spaceship from another planet, but it usually is an airplane, weather balloon, bird, or some other terrestrial object.

I don’t disagree that “yoo-eff-oh” is the common prounciation, but I have also heard this pronounced “yoo-foh” (which I see is given as an alternative in some dictionaries).
