Pronunciation: [ɪn mˈɪdə͡l ɒv] (IPA) 
The phrase "in middle of" is often spelled incorrectly, with "of" sometimes written as "off". This mistake may be due to the way the word is pronounced. In IPA phonetic transcription, "of" is pronounced as /ʌv/, with a short "u" sound and a "v" sound at the end. This may lead some people to spell it as "off", with a double "f" representing the final sound. However, the correct spelling is "of", with a singular "f" at the end.
The phrase "in the middle of" is a prepositional phrase commonly used to denote the position or state of being at a point that is equidistant from either end or sides of a particular space, time, or event.

It suggests being in a state of transition or ongoing activity, where there is still progress to be made or further development to occur.
When used with spatial references, "in the middle of" signifies being at the midpoint or center of a physical area or object.
