There is a question about the blog from earlier in the week: What happens when the spelling is interrupted or picks up midword?
It is important to remember that the hyphen goes with the letter that follows it, not with the letter in front of it. (Otherwise, there would be a hyphen in front of the first letter of the spelling. Think about it.) So if there is an interruption and the spelling continues, it looks like this:
…My name is Russell, R-u-s-e — -s-s-e-l-l.
…It is Jaffe. That is -f-f-e.
The spelling which is midword starts with a hyphen before the letter.
