No, I didn't omit the i. I picked up the Scots Dictionary that Jo gave me, thinking I might find an interesting word for Miscellany, but stopped at the pronunciation guide and got jolted to a halt. It says:
ng in Scots, eg hunger, ingle, ingan, is almost always pronounced as in English sing, not as in English single . For the life of me, I cannot hear any difference between the two ng's. What is it that I'm not knowing? As far as I'm concerned, the first four letters of both are pronounced exactly the same way; it's just that a hard g gets added to form the second syllable of single.
