English spelling is very consistent. You know I before E except after C or in any word like Height or Weight or .....
In school we had to do a book review on a book of proper English - I thought the author was George Bernard Shaw but I cannot find it in his listed works.
The author gave many examples of PROPER English spelling and the one I always liked best was fish, in proper English spelling, is ghot
- GH is the F sound in many words like enough
- O is the I sound in words like women
- T is the SH sound in words like station.
Therefore either I (or O from the example above) for the first letter of Inshitification is perfectly correct.
