When writing dialogue for characters that stammer or stutter over the first letter of the first word in their speech, should the first letter remain a capital or become lowercase when repeated?
My question is probably best explained by example…
Retaining capital letter:
“H-H-Hello,” he said.
Not retaining capital letter:
“H-h-hello,” he said.
Which is correct? Are both acceptable? I wasn’t able to find any solid information either way, so I thought a discussion could be had in the hopes of reaching a concrete conclusion.
To be entirely clear, I’m only asking about stammering over the first letter of an otherwise uncapitalized word, and whether that repeated first letter should stay capitalized or not.
