I am confused by this one - Nicola. I have always pronounced it 'Nickolah' in one mouthful (IYKWIM) but twice recently I have heard people pronounce it as 'Nicole-ah'.
I think 'Nickolah' is for a girl and 'Nicole-ah' is for a boy. Nicola Finetti the fashion designer is a guy and his name is pronounced 'Nicole-ah'.
